You would love California. Your boys would love Carsland, the Indiana Jones ride...Space Mountain currently has an awesome Star Wars overlay, plus they have a ton of dark rides out there, like Monster's Inc, Pinnochio, Mr. Toad's Wild Ride, Alice in Wonderland, Snow White, Rodger Rabbit...tons to do. If I can take a vacation this summer, I'm actually thinking maybe going on the DL trip with my parents and then just a long weekend in WDW...long enough to swim in Stormalong Bay, see the new AK stuff, and hop on TofT. Then I would go back to WDW with them in the winter.
The setup of DL is more like Uni, from what I understand. The parks are less than a football field away from one another, and DTD is right there next to the parks. There's plenty of good neighbor hotels that are super close. As in, walk across the street and you're there. There's also more rides in each park than the WDW parks.
Uni out there, from what I understand, isn't as good as Orlando, but it's an actual working studio, which is neat, and they still have Harry Potter World there. You could probably make a day out of it. There's also other parks out there, too, plus beaches.
