No matter who you invite, a few characters always show up, sometimes literally the same people from someone else's wedding you were both at. They're not a problem to solve. They're most of the fun. Here's who to expect, and how to plan around them without losing your mind.
The second the band plays anything with a beat, this person is out there organising a circle, a line, or a full Siege of Ennis whether the room asked for it or not. By 11pm they've taught three strangers the steps and recruited your granny.
Give them room, literally, when you're picking a venue with a dancefloor. This is not a corner-of-the-room activity.
RSVP'd solo, then two weeks out asks if they can "just bring someone." Sometimes it's a partner you didn't know existed. Sometimes it's a plus-one's plus-one.
Decide your policy early and hold the line kindly. "We'd love to, but we're locked in on numbers with the caterer" works on everyone, and is, helpfully, usually true.
Invite said adults only, in the actual wording, not just implied. They bring the kids anyway, usually with a cheerful "ah sure they'll be no bother."
And they're often right, right up until the flower girl's little brother makes his own surprise entrance during the vows, or someone's toddler is passed out under the top table by half nine.
Put the policy directly on the invite itself, not buried on the wedding website where half your guests won't look. And if a kids' table is happening for the ones who are invited, decide that early. It's one of the few seating calls that changes everything else about the room.
Was fully on board for "three courses and a few pints" when you sent the save-the-dates. Eighteen months later they RSVP with a plate that's mostly the vegetables, wave off the bread basket, and nurse one glass of wine the whole night, no judgement, might genuinely be having the best night in the room.
Catering headcounts are still catering headcounts though, so keep dietary and portion notes genuinely up to date right up to the final numbers. Appetites are shifting faster than any invite template accounts for these days.
Confirmed chicken on the RSVP back in March. Announces a brand new dietary situation to the wedding coordinator at the actual reception. Every caterer has seen this exactly once too many times.
It's not really solvable, but a clear, simple way to update dietary info right up until the week of the wedding at least catches most of them before the seating chart and final catering numbers are locked.
None of this is really a guest problem, it's a planning-for-humans problem, and it's exactly why a rigid seating chart or a guest list kept in someone's head falls apart by week two.
MarryHQ's guest list and seating planner are built to flex when the plus-one count changes or the dietary notes update the day before, so the characters stay charming and the logistics stay sane.
