Wow, this could be a long list, but I'll try to narrow it down!
MK: Spectromagic, Wishes, Splash Mountain, Pirates of the Caribbean, Big Thunder Mountain, Haunted Mansion, Peter Pan, Philharmagic, Buzz Lightyear Space Ranger Spin, Space Mountain
AK: Kilimanjaro Safaris, Kali River Rapids, It's Tough to Be a Bug, Festival of the Lion King (We also love Jammin' Jungle Parade although others don't)
Epcot: Test Track, Journey Into Imagination, Spaceship Earth, Illuminations, and a stroll (or two) through World Showcase, American Adventure
MGM: Rock-n-Roller Coaster, Tower of Terror, Great Movie Ride, One Man's Dream (for a glimpse into a real genius), and Fantasmic
There is so much more, but those would be our absolute favorites!
