So once you've gotten everyone's lists and made some sort of idea of what you'd like to do, now's the time to assemble. Get your genie+ reservations made and decide what time to get to the park (buses are reliable, but leave earlier than you think you need to. Like an hour+ before you actually want to be stepping in the park.
Try to have some sort of plan as far as where to start and end so you aren't bouncing back and forth across the massive park- It gets exhausting!
This may seem wild, but here is what a normal Itenerary may look like for a jam packed MK day.
6:30 - Awake
6:55 - double check boarding group for Tron
6:59 - refresh refresh refresh that app
7:00 - grab your boarding group!
7:30 - Breakfast in room / Resort
8:00 - get in line for buses
9:00 - Park Open (possibly an 8:30 park open if you have early park hours with your resort stay!)
9:00 - Welcome Show
9:15 - Start in whatever land you want, but hop in line for the highest wait time first and get it out of the way (Mine Train, Space Mtn, Jungle Cruise Etc.)
We suggest allowing yourself at LEAST an hour per ride wait in your schedule, some rides more and some less. Pirates? Less. Space Mountain? More. and keep checking that app for those wait times and down times. This is how the rest of MY day personally will go...
9:30 - Mine Train
11:00 - Winnie The Pooh
12:00 pm - Snack Break / Lunch
12:45 - The Little Mermaid
1:30 - Small World
2:00 - Haunted Mansion
2:45 - Line up for parade in frontierland
3:00 - Parade
3:30 - Tron Boarding Group
4:30/5 - Space Mountain
6:15 Peoplemover
7:00 - Monsters Inc. Laugh Floor/ Carousel of Progress (you pick!)
7:30 - Buzz Lightyear OR Snack time :-)
8:00 -Barnstormer/Dumbo/ Tea Cups (you pick!)

9:00/ 9:15 - Happily Ever After
9:45 - fight the crowds over to adventureland
10:00 - Jungle Cruise / Pirates of the Caribbean / Big Thunder Mountain Railroad
10:45 - Depending on waits mayyy be able to hop in line for one of the above. Or speed walk it across MK for a spin on something else again. As long as you get in line before the park closes (on this day aka 10:59) you get to ride!
11:30 - Shopping, bussing, monorailing, etc. back to your resort :)
