There is so much to see and do at DHS, that we have to spend 1 and 1/2 days to do it all. We love TSM, MuppetVision, Star Tours, The Great Movie Ride, Aeriel, Indiana Stunt Show, ToT and RnRC (DH and DD8 are huge fans), The whole Animation area (we could spend hours alone there), haven't done B&B yet; but that is on our to do list for December, and love going into all of the shops.
In all fairness, we used to only give this park a 1/2 day of our time, but this is when our kids were littler and we were only interested in MuppetVision and Playhouse Disney. Now that they are older, they love doing all of the shows and rides....it is truely a wonderful park to visit.
