A few that I can think of:
Our trips have always started somewhere in the last two weeks of Sept, and must be on site
Must rope drop MK to see the park opening show!

Last full day is MK. Gotta end with the best, even though it tends to be a little sad on that last night.

Once each kid is tall enough to ride RnRC we get a photo of them in front of the big guitar while giving the "hang loose" sign
Beside the headliners, some must do “less popular” attractions: People Mover, HoP, Sum of all thrills, Turtle Talk, Animation Academy
Sharing a low carb Monster Energy Drink in the mornings
Hitting the resort pool after a full day at the park.
A mixed drink by the resort pool at night
Food related:
Arrival afternoon/evening is spent at Epcot with dinner at Coral Reef
At least one HS day includes a boat ride to the Beach Club and Cape May’s
At least one MK day includes a monorail ride to the Polynesian and Ohanas
At least one MK night is spent sticking around after park close/Wishes and having a treat from the bakery (ice cream, cookie, etc…) and waiting for the crowds to disperse. So relaxing.
AK lunch at Flame Tree BBQ (preferably in the outlook area down by the water/river)
A new fav is BOG lunch, and Columbia Harbor House is still a must do for lunch at MK, and Sunshine Seasons at EP
