See, to my kids, the theming at AS Movies blows away the theming in the Universal pic. The way they look at the Andy's Room courtyard is like they've entered kid heaven. They wouldn't be overly impressed by the theming in the above pic of Universal at all. Sure, they'd love the slides and (hopefully - I don't know if they have one) kiddie swim area, but they're big on water play anyway. (Just ask Great Wolf Lodge...hubby and I aren't fans, but they both love it so we're soon going for the second time in less than three months.)
We've stayed at both CBR (pirate room) and AS Movies, and while they loved the main pool and splash area at CBR and could have spent days doing that without even entering the parks, they made sure both my husband and I knew that they missed Movies because of the theming. Personally, I'd rather stay at CBR or Port Orleans because they have theming style I prefer and the convenience of buses...but that's me.
