kid's birthday party, two weeks out to cleanup

the timeline I actually use. adjust the venue steps if you're doing it at home

01
Pick a date and a headcount cap
earlier than you think, especially for weekend slots at popular venues
02
Book the venue or clear the space at home
03
Send invites (2 weeks minimum notice)
04
Order the cake
get it in writing what flavor and how many it feeds, bakeries mix these up more than you'd think
05
Plan the food - keep it simple, kids barely eat at these
06
Buy decorations and a theme-appropriate tablecloth
07
Confirm RSVPs, follow up with the stragglers
08
Plan 1-2 activities plus a buffer game
always have a backup, the planned craft flops about half the time
09
Order or wrap the goodie bags
10
Buy candles, lighter, and a knife for the cake
11
Prep the playlist
12
Charge the camera or phone, clear storage
13
Pack the party bag: tape, scissors, extra plates, trash bags
you will run out of one of these, every time
14
Day before: pick up cake, ice drinks, set up what you can
15
Day of: set up 90 minutes before, not 30
16
Cleanup: bag trash immediately, return rentals within 24 hours
the rental place charges a late fee after a day, learned that one the hard way
