How Far in Advance Should You Start Planning a Family Reunion?

"We started planning in March for a July reunion" is a sentence I hear at least a dozen times a year, usually said with a mix of pride and exhaustion. Four months sounds like plenty of time until you're trying to find a hotel room block in a town with one Holiday Inn Express, or you discover the shirt vendor needs three weeks and you've got twelve days left. Twelve years of doing this has taught me the number that actually works: 12 months out for a mid-to-large reunion, 6 months minimum for something small and local. Here's what that year should actually look like.

12 months out: pick the date and lock the venue

This is the unglamorous, unskippable step. Before anything else, somebody — one person, not a committee vote that drags for six weeks — needs to pick a date. I recommend avoiding major holiday weekends unless your family has always done it that way, since flights and hotels spike in price and availability tightens fast. Once the date's set, get the venue deposit down. If you're leaning toward a hotel or resort, this is also when you start the room block conversation, because good properties in popular areas book out that far for summer weekends. If you skip ahead to month six thinking you'll "just wing it" on the venue, you'll wing it into whatever's left, which is rarely what you wanted.

9-10 months out: build the guest list and open communication

Now you need real names, real addresses, and a way to reach everyone — a group text is fine for close family, but for anything past about 40 people I push families toward a simple shared spreadsheet or a free event page where RSVPs and contact info live in one place. This is also the stage to start the "have you heard from cousin Marcus" detective work, because tracking down relatives who've moved, changed numbers, or fallen out of touch takes longer than anyone expects. I had one family spend four months just locating a great-aunt who'd moved to three different states in five years. Start that search early or you'll be sending invitations to an address that hasn't been current since 2019.

8 months out: nail down lodging for out-of-town family

If your reunion draws people from multiple states, this is when you want a lodging plan solidified, whether that's a negotiated hotel block, a list of nearby short-term rentals, or an Airbnb split between families. Waiting until three months out means the good options are gone and the remaining rooms cost more. This is a repeat of a mistake I see constantly: families nail the venue but forget that half their guests need somewhere to sleep, and by the time they think about it, the only rooms left are 25 minutes away and $60 a night more expensive.

6-7 months out: menu, activities, and the budget gets real

This is when food planning starts in earnest — caterer quotes, potluck sign-up sheets, or a decision about whether the venue has kitchen access at all. It's also a good time to nail down the day's activity flow: a group photo slot, a kids' game block, maybe a talent show if your family is that kind of family. Mine is. Budget should be firmer by now too, with actual numbers instead of guesses, because the next few decisions all cost real money.

5 months out: order apparel and keepsakes — yes, really, this early

Here's where most families get it wrong, and it's the mistake I harp on more than any other. People treat event shirts and keepsakes like a task for "closer to the date," and then they're stuck ordering three weeks out, paying rush production fees, and discovering that half the sizes they need are backordered because everyone waited to submit their size until the last minute. Apparel production takes real lead time — design proofs, size collection from 80 different people who are famously slow to respond to a form, printing, and shipping. Five months out is when I tell families to start collecting sizes and get a quote locked in, even if the final headcount isn't 100% settled yet. Most vendors, us included, can work from an estimated count and adjust before the final order goes to print.

This is also when to think through what you actually want. A basic tee works for almost everyone, but plenty of families upgrade part of the order — hoodies for a fall reunion, a run of custom pens or glassware for a milestone anniversary edition, or a mix of both. Check t-shirt options and lead times directly so you know what window you're working with before you commit to a design.

3-4 months out: finalize headcount and confirm every vendor

RSVPs should be firming up now. Send a hard deadline for responses — "let us know by [date] or we'll assume you're not coming" sounds harsh but it's the only thing that actually gets stragglers to respond. Confirm your caterer, your rental company, your photographer if you have one, and double-check your venue contract for anything you might have forgotten, like whether alcohol is allowed or whether cleanup is your responsibility.

6-8 weeks out: submit final apparel order and print anything with a date on it

If you didn't order shirts at the five-month mark, this is your absolute last comfortable window, and even then you're pushing it for a large group with size variety. Standard turnaround plus shipping eats time fast, and rush fees on group apparel orders can add 20-30% to the cost for the privilege of a two-week turnaround instead of four. This is also when programs, name tags, table signage, and any printed itinerary should go to design and print.

2-3 weeks out: confirm final numbers with every vendor

Call the caterer with your final count. Confirm the room block cutoff hasn't passed. Print the day-of schedule. Send a reminder email or text with parking info, dress code (if your family does a themed color day), and start time, because someone will still ask "what time does this start" the day before despite three previous emails.

Week of: the boring stuff that saves the day

Pack a reunion box: extra pens, tape, a first-aid kit, phone chargers, cash for tips or last-minute purchases, and a printed copy of every vendor's phone number in case your phone dies. Assign two or three people specific jobs for setup and breakdown so it's not all falling on whoever organized the thing, which is usually one exhausted person by this point. It's usually me, in my own family's case, so I say this with real feeling.

The honest minimum

Could you pull off a 40-person backyard reunion in eight weeks? Sure, I've seen it done. But anything over 75 people, anything involving a hotel block, or anything where you want matching apparel without paying a rush premium needs closer to a year. Twelve months feels like a lot of runway when you start, and somehow it's never enough by the time you get there. That's not a knock on your planning — it's just how many small decisions a reunion actually has hiding inside it.
