We all know weddings don't happen on time, but this is our best guestimate on the days festivities:

3:00pm: Guest who are staying overnight can check into their treehouse
3:30pm: Guest can arrive (who are not staying at the venue overnight)
4:00pm: Wedding begins
4:30pm: Cocktail hour
4:30pm: Family and Couple photos
6pm: Dinner followed by reception
9pm: Late night snacks
10:00pm: Bar and music end
11:00pm: All non-overnight guests must depart
1:00am: Curfew for all overnight guests

Following morning overnight guests must check out by 11am (breakfast will be served as well)
