Add everybody who is coming — including the ones who will say they don't mind.
Before anybody fills in a sheet and long before anybody packs. Not what it was when it was booked — what it now is, given who is actually coming.
The last one is not a formality. A booking made two months out was made for a family that may not exist any more, and nobody reopens it — because saying something has changed sounds, to the person it is about, like being counted as a problem. Write it down instead of minding it.
Decide, plan, pack — in that order. Packing is the last step and it is the one most people start with.
One person can fill in everybody here. If people would rather do their own, open this file on their device, fill in a sheet, then use Copy my sheet at the bottom of it and send you the code. Paste it below to add them to your party.
Everything is stored in this browser only — nothing is uploaded and nobody else can see it. Clearing your browser data will remove it.
Pick whose sheet this is, then answer for yourself — not for the group.
Where the sheets agree is the shared day, and nobody had to win it.
A shape, not a timetable. It is built from the hours people actually gave you.
