Your First Company Offsite as an EA: The Complete Checklist

By the Vantly team · Research checked October 2026

Someone just forwarded you a calendar hold that says "Company offsite" with a date, a rough headcount and a goal like "get everyone aligned." Congratulations: you are now the event planner. Nobody hands you a checklist for this, so here is the one we wish every first-time organizer had. Three tools make a first offsite survivable: a timeline that tells you what to do this week, a master tracker that holds every person's room, dietary needs and travel in one place, and a rule that there is one organizer and one venue contact. Everything below hangs off those three.

Someone just forwarded you a calendar hold that says "Company offsite" with a date, a rough headcount and a goal like "get everyone aligned." Congratulations: you are now the event planner. Nobody hands you a checklist for this, so here is the one we wish every first-time organizer had.

Three tools make a first offsite survivable: a timeline that tells you what to do this week, a master tracker that holds every person's room, dietary needs and travel in one place, and a rule that there is one organizer and one venue contact. Everything below hangs off those three.

This guide is written for executive assistants planning a 30–80 person offsite for the first time, usually on top of the day job. Office managers, People Ops coordinators and founders at small companies will find it just as useful. Examples lean US and New York, but the checklist travels.

Start here: get the brief and the budget in writing

The most expensive mistakes on a first offsite happen before you contact a single venue. They come from a vague brief that changes three times. Before you search for anything, get five answers from your executive, ideally in an email you can point back to:

  • Purpose. What should be different after the offsite? Strategy alignment, team bonding, a planning sprint and a celebration all need different rooms and agendas.
  • Headcount. A firm number, a likely range and who is definitely invited (full company, a department, leadership plus guests).
  • Dates. Fixed dates, or a window you can trade for better availability.
  • Budget ceiling. One total number, and whether it includes travel, alcohol and gratuities.
  • Approver. The one person who signs off on the venue, the contract and any spend above the ceiling.

Write the purpose as one sentence at the top of your planning doc. It will settle arguments later, from "do we need a pool?" to "can we skip the second workshop?"

If you cannot get a budget number, offer two or three options with clear trade-offs and ask your approver to pick one. A choice is easier to get than a number.

The offsite planning timeline

How far ahead you need to start depends on group size, season, destination and whether people sleep over. The ranges below are a common planning rhythm, not fixed lead times. Popular dates and whole-property buyouts often go early, so start sooner rather than later.

When (rough guidance) | Key tasks | Owner

As soon as you are handed it | Brief, budget, dates, approver in writing; start the master tracker | You + executive

Early: often 3+ months out for overnight groups | Shortlist destinations and venues; site visit or video walkthrough; hold dates | You (+ planner if using one)

Once the venue is chosen | Sign the contract; confirm room setup, dining model and cancellation terms | Approver signs, you manage

Mid-stage: roughly 6–8 weeks out | Send the attendee form; draft the agenda; book transport and activities | You

Roughly 3–4 weeks out | Final rooming list; dietary and accessibility list to the venue; travel confirmations | You + venue contact

The week before | Final headcount; run-of-show; transport manifest; packing list | You

The day before and day of | Reconfirm everything; arrive early; run the room | You + venue contact

If your dates are only weeks away, the order stays the same. You compress each step and make faster decisions, which is often the moment to bring in help (more on that below).

Build one master tracker

Rooming in one spreadsheet, dietary needs in an email thread, flights in someone's Slack DMs: this is how details get lost. Build one master tracker on day one and make it the only source of truth.

Suggested columns:

Column | What goes in it

Name and team | As it should appear on name badges and the rooming list

Room | Assigned bedroom, building and bed type

Dietary | Allergies (severity noted), restrictions, preferences

Travel | How they are getting there: flight, train, shuttle, own car

Arrival and departure | Date, time and flight or train number

Accessibility | Mobility, room location, quiet space, any other needs

Emergency contact | Name and phone

Notes | Roommate requests, late arrival, leaving early

Collect the information with one short form, not a dozen emails. Send it once, set a deadline, then chase only the gaps. Treat dietary and medical details as sensitive: limit who can see the tracker and share only the relevant columns with the venue or kitchen.

Choosing the venue: the checks that matter

Beautiful photos are the easy part. These are the checks that save a first offsite.

Count bedrooms, not mattresses. Many listings say a house "sleeps 30" by counting bunks, sofa beds and shared beds. Most corporate teams expect one person per private bedroom. Count bedrooms from the floor plan or room photos, confirm each has a real door and a clear bed type, and treat bunks and sofa beds as overflow rather than capacity. Ask early whether anyone is expected to share. Leadership usually is not.

Get three capacity numbers. A venue has a number for sleeping, a number for meeting and a number for dining together, and they are rarely the same. A house might sleep the group comfortably while the main room only seats part of it for a workshop. Your comfortable group size is the lowest of the three. If one falls short, plan the fix out loud, such as a nearby hotel for overflow or an off-site dinner, rather than discovering it on arrival. Ask: if we grow by ten people, what breaks first?

Ask: buyout or room block? A full-house exclusive buyout means no other guests on site. A soft room block means other guests may share the lobby, breakfast room and grounds. A soft block or soft hold is not an exclusive buyout, whatever the listing calls it. Ask in writing which one you are getting, which shared spaces stay public and when unpicked rooms are released.

Test the WiFi before you trust it. "High-speed WiFi" on a listing is not a guarantee. Ask whether bandwidth is dedicated to your group, run a speed test in the meeting room with other devices connected, and find out who resets the router if it fails on a Saturday morning. For the full checklist, see How to check a venue's WiFi before your offsite — /guides/how-to-check-venue-wifi-for-corporate-offsites.

Check the drive time honestly. From New York City, many country houses and estates are roughly 2–2.5 hours door to door (estimate; check the real day and time of travel). That is a great overnight distance and a tiring day trip.

Food, transport and the program

Ask who is cooking. Find out the dining model before you sign. Is it an on-site restaurant, a private chef using a commercial kitchen, or dinners at restaurants in town? Can the whole group eat together in one room? What is included, and what is extra, such as the bar, wine or service charges? Send the dietary list to whoever is cooking as early as they ask for it, then reconfirm it the day before.

Shuttle or rideshare? For a small group in the city, rideshare can work. For 30 to 80 people heading to a rural venue, dozens of separate rides tend to mean staggered arrivals, surprise costs and a pile of expense reports. A chartered coach or one or two Sprinter-style vans usually make the day calmer. Before you book, check:

  • Room for luggage and any AV cases, and parking at the venue
  • Pick-up points and times from the office, the airport or a station
  • A late-arrival plan: a second shuttle run or an approved rideshare allowance
  • Who the billable counterparty is: one transport vendor, or forty individual expense claims

For more on vans, coaches and late arrivals, see How to move 20–50 people to a company offsite — /guides/group-transport-for-company-offsites.

Build an agenda with air in it. First-time agendas are almost always too full. Put the most important session in the morning when energy is high. Leave real downtime in the afternoon, end the formal program before dinner, and plan one optional activity rather than three mandatory ones. People remember the walk and the long dinner as much as the workshop.

Vendor wrangling: one organizer, one venue contact

The fastest way to lose control of an offsite is for five colleagues to email the venue directly. Set the communication rules early:

  • You are the single point of contact for the venue, caterers, transport and activity vendors. Colleagues send requests to you, not to vendors.
  • The venue names one contact for your group, plus a backup for the event days.
  • Write down who can approve spend. Your approver signs contracts and anything above the ceiling. Agree a small threshold you can approve yourself so minor changes do not stall.
  • Confirm changes in writing. A phone call is fine. Follow it with a short email that says "to confirm."
  • Keep one vendor list with contacts, deposit and payment dates, cancellation terms and on-the-day phone numbers.

The week before and the day before

The week before

  • Lock the final headcount and update the master tracker
  • Send the final rooming list and dietary list to the venue and kitchen
  • Share the run-of-show with the venue contact and every vendor
  • Send attendees a short "know before you go" note: address, timings, what to pack, dress code and who to call
  • Confirm the transport manifest, pick-up times and the late-arrival plan
  • Confirm AV, room setup and a test slot in the meeting room
  • Print or download key documents: contracts, contact sheet, tracker, agenda

The day before

  • Reconfirm arrivals with transport and the venue
  • Reconfirm dietary needs with whoever is cooking each meal
  • Charge everything and pack your kit: adapters, chargers, extension cord, pens, tape, basic first-aid items
  • Share your phone number with attendees and the venue as the on-site contact

When to hire help

Plenty of EAs run a great first offsite in-house, especially a day event or a small overnight at a venue the company already knows. But a few signs suggest the load has outgrown a side-of-desk project:

  • The offsite involves overnight stays and a destination you do not know
  • The group is large enough that rooming, dietary needs and transport become real logistics
  • The dates are close and decisions need to happen faster than you can research
  • You need true privacy, a buyout or a venue whose capacity numbers you cannot verify yourself
  • Your day job is already full, and this would land in your evenings

That is the work of a local event designer who already knows the destination. They know which houses really have enough private bedrooms, whose WiFi survives a workshop and which dining rooms seat everyone together. At Vantly, local event designers shape a tailor-made offsite around your goals, group and budget, and absorb the invisible work: rooming, kitchen briefs, transport and vendor coordination. One point of contact and one invoice is how we aim to work. Our sample events show what that can look like. Treat them as starting points a designer tailors, not fixed packages.

FAQ

How far in advance should you plan a company offsite?

Start as soon as the date and purpose are confirmed. For an overnight offsite of 30 to 80 people, many planners begin a few months ahead, because whole-property buyouts and popular dates go first. Shorter timelines can work. They just need faster decisions, a tight shortlist and often outside help.

What should be on an offsite planning checklist?

A written brief and budget, a timeline, one master tracker for attendees, venue checks (private bedrooms, three capacity numbers, buyout terms, WiFi), the dining model, transport, an agenda with downtime, vendor contacts and payment dates, and a week-before and day-before list.

How do you track rooming, dietary and travel for 50 people?

Use one master tracker with a row per person and columns for room, dietary needs, travel, arrival time, accessibility and emergency contact. Collect the details with one short form and a deadline. Limit who can see sensitive details, and share only the relevant columns with the venue.

Shuttle or Uber for a group offsite?

For a small group in the city, rideshare can be fine. For a larger group heading to a rural venue, a chartered coach or Sprinter-style vans usually arrive together, carry luggage and AV, and give you one vendor to pay. Plan a second run or a rideshare allowance for late arrivals.

Who should be the single point of contact with the venue?

One organizer on your side, usually the EA running the offsite, and one named contact at the venue. Colleagues route requests through the organizer, changes are confirmed in writing, and only the agreed approver signs contracts or spend above the budget ceiling.

When should I ask for outside help?

Ask when the offsite is overnight in an unfamiliar destination, the group is large, the dates are close, or the work would spill into your evenings. A local event designer can handle venue checks, rooming, kitchen briefs, transport and vendors, so you keep oversight without carrying every detail.
