Must -dos for us:
MK:
Philharmagic - adorable, great Disney music, and no need for FP.
Celebrate the Magic - projection show on castle, so amazing, find a good spot with center view of the castle for best view.
Wishes - MK fireworks, just classic Disney - watch for Tink to fly at the start(weather permitting).
AK:
Lion King show- Broadway quality performers, acrobats, music - lot of fun
Discovery Trails - there are trails that go close up to the tree of life that aren't well marked but you can ask a CM - very cool to see all the animals carved in the tree.
Devine - this is a woman who is made-up to look like a tree covered in vines, and you can walk by her without even noticing, the camouflage is so good. You can ask a CM if she is around that day, and where you might see her. The last time she was in the Oasis early in the morning.
Safari - a ride I know, but closet I can get right now to going to Africa! Giraffes and elephants are awesome, and sometimes the male lion is up. FP or early morning or both - no two rides the same.
HS:
TSMM - I know this is a ride, but the queue is so well done and one of the few interactive rides, such a fun game, much better than Buzz in MK (IMHO) - need a FP or do early at RD.
Indiana Jones - fun stunt show
Fantasmic- great night show
Sci-Fi - again, not a ride, but a fun experience to eat in a car at a drive-in
Epcot:
Soarin - another ride, but the feeling of flying is amazing, seeing places along with smells (I assume this is still the case with the new movie)
The Seas - my fave, the manatees are here, along with dolphins and other fish exhibits.
World Showcase - performers in different countries you can watch - the show in Italy was hysterical - i think they were called some kind of sisters - DD got picked to perform along with others from the crowd, really entertaining.
