MK has Dream Along with Mickey, on the castle stage, multiple times a day, characters, princesses and dancers. They've also got a lot of "roaming" entertainment, Majesty makers in Fantasyland, (currently & temporarily) pirates in Adventureland, Dapper Dans do sets along main street, Cap Jack has pirate tutorial in Adventureland.
Epcot has a stage in Canada, had lumberjacks before xmas but it's changing. They've also got various performances around World Showcase, no real "scripted shows" per say but lots of entertainment. My favorites include the band in the UK, American Music Machine & Voices of Liberty!b
