We will only be there for four nights! Was planning on doing an Epcot half day, animal kingdom day, magic kingdom day, and Universal.
Ok in that case, you’ll want to take into consideration what you could all conceivable hit in a single day. I don’t know you and your grandma, but mine’s 90, and isn’t going to able to pop all over the park. Even at 67, my mother would have difficulty popping all over the park. Given the rides you wanted to hit:
...
-Under the Sea- Journey of The Little Mermaid
-Peter Pan's Flight
-Winnie the Pooh
-Small World
-Philharmagic
-PeopleMover
-Buzz Lighter
-Pirates of the Caribbean
-Jungle Cruise
-Liberty Square Riverboat
-Haunted Mansion
-Country Bear Jamboree
I’d probably cut Buzz and the PeopleMover off your list. If you hit them, great, but chalk them up to your ‘expendables’ since they’re a bit removed from the rest of your list. This leaves you then with a couple of choices, depending on what her favourites are:
Option 1:
jungle cruise, Pirates, Country bear, Liberty boats, Haunted, Small world, Peter, Mickey’s phil
with mermaid and Pooh in reserve, followed by people and buzz if she’s able.
Option 2:
straight back to
mickey Phil, Peter Pan, small world, haunted, liberty, country bear, pirates, jungle,
then you can either cross to tomorrow for buzz, people, or head up the east side of the castle for pooh,mermaid
Option 3:
cut to the right of the castle, Pooh, mermaid, then follow the route of option 2,
Or, if Buzz or People are your top priorities, then option 4:
Buzz, people, Pooh, mermaid, then follow option 2, but figure you might not hit liberty boats, country bears, pirates and jungle cruise.
And of course, for any of these routes, once you picked the path that hits the attractions in the order that’s important to you, (and grandma) then you plan your FP accordingly. Like, Peter , since you basically need a FP for to avoid long lines, if you go option 2, you want an early FP, option 1, maybe an early afternoon for it, option 3, late afternoon or 4, early evening.
Try to plan walking speeds, need for breaks, food, etc, and have a ‘plan’ for the day. Be sure to build in some flexibility too because no matter how well you plan, inevitably, something always throws your plans out of order.
