MK - Carousel (but on a horse that goes up & down)/ Haunted Mansion, EPCOT - Mission Space, DHS - Rock 'n Rollercoaster, AK - Expedition Everest
The carousel may not be the best ride there, but it brings back a lot of fond family memories - that's why it's my "sentimental" favorite. My "regular" favorite would be HM.
Haunted Mansion, Soarin', Tower of Terror, Expedition Everest. I had a hard time picking between HM and Peter Pan, but last time we skipped Peter Pan and I managed to live without complaining too much.
