How to Organise a Holiday Party
Step-by-step guide to organising office Christmas parties, neighbourhood events, and family gatherings. Handle RSVPs, dietary needs, plus-ones, and Secret Santa with ease.
Organising a holiday party for your office, neighbourhood, or family? This guide walks through everything from managing dietary requirements and plus-ones to coordinating Secret Santa — with practical tips from organisers who've been there.
Before booking anything, decide what kind of holiday party you're running. An office Christmas party has different requirements than a neighbourhood New Year's Eve bash or a family Thanksgiving dinner.
Choose your holiday and style
Office Christmas party? Halloween block party? Family Easter brunch? Your holiday determines timing, theme, and guest expectations. Formal sit-down dinners need 8-12 weeks lead time; casual drop-in parties need 3-4 weeks.
Decide on plus-ones upfront
Will people bring partners? Kids? This single decision affects your headcount by 50-100%. Office parties often allow a plus-one; neighbourhood events are usually family-friendly; adult-only events must be crystal clear from the start.
Set a realistic capacity
Holiday parties always run bigger than expected. If your venue holds 50, cap RSVPs at 40. Account for plus-ones, last-minute tag-alongs, and the fact that saying no at the door ruins holiday spirit.
Pick your food format
Sit-down dinner, buffet, or potluck? This decision drives your venue choice, budget, and how you'll handle dietary requirements. Potlucks spread the work but make dietary tracking harder.
Frequently asked questions
How do I collect dietary requirements without a spreadsheet nightmare?
Use Who's In to add a required RSVP question for dietary needs. Every guest must answer before confirming. You get a clean list of all requirements in one place, exportable for your caterer. No chasing people individually.
Should I allow plus-ones to my office holiday party?
Most companies allow one plus-one for Christmas parties — it feels more special and partners appreciate being included. Set the expectation clearly in your invite: 'You plus one partner/guest'. Require plus-one names in RSVPs for accurate catering.
How far in advance should I start planning a Christmas party?
Start 10-12 weeks ahead. Venues book out by October for December parties. Send invites 8 weeks before, set RSVP deadline 2 weeks before, and finalize catering 1 week before. December is the busiest month for party venues — early planning isn't optional.
How do I coordinate Secret Santa with RSVPs?
Add a separate RSVP question for Secret Santa participation. Not everyone attending wants to participate, and you can't draw names until you have the final list. Set a clear gift budget (£15-25 is typical for offices) and deadline for bringing gifts.
What's the best way to handle venue capacity for a neighbourhood party?
Set capacity 20% below the venue maximum to account for kids, plus-ones, and the reality that saying 'we're full' at the door kills holiday spirit. Use Who's In to set a waitlist if you hit capacity. Most neighbourhood parties should plan for 30-50% more people than RSVP yes.
