My vote goes to DCA. We went to USH when my oldest was around a year old and found there wasn't very much for her do there. But DCA has a ton to do and can keep us busy all day. My girls love the Playhouse Disney show and there a normally tons of Playhouse Disney characters out in the Backlot area (we've met JoJo, Goliath, and Stanley). Other characters we've seen around there include Chicken Little, Donald, Sully (Monsters Inc.), the Incredibles, Snow White, Cruella De Ville, Hercules and Cinderella, Mickey and Woody make an appearance at Drawing Show thing. They like the Monsters Inc ride, the Muppet 3-D show, It's Tough to be a Bug show, the water play area and the kids section. We've done dinner at Ariel's Grotto and it's been great.
