It depends what hotel. When I stay at the Beach Club, I go to Spoodles for dinner, then go to Epcot to see Illuminations, and generally sneak in a ride on Figment.
At Wildnerness Lodge, Eat at Whispering Canyon, then go down to the beach for the electric water parade and watch Wishes from across the water.
At the Polynesian, Go to MK for dinner, then watch Spectromagic and Wishes.
At the Swan/Dolphin, Ride rock n roller coaster and Tower of Terror, go to Hollywood Brown derby for dinner, and watch Fantasmic.
All of these following a swim, of course.
This is the extent of resorts I have stayed at, Saratoga Springs to be added in June.
