Hope you both have a great time on your trip!! Your plans sound great. I just want to say one thing, and this is just MY opinion and I know not everyone agrees, but I'll say it lol....not sure if you've done Disney Quest before, but we tried it last time we went and were quite disappointed with it. Just seemed like we paid a lot to get in and then there wasn't much of anything to do. I would say that was the only thing we considered a waste of money on that entire trip. But there were people there having fun, so it might just come down to what types of games you like. But I just wanted to say that.
I wanted to eat at T-Rex this trip, but DS is terrified of Rainforest Cafe and I know they are similar, so we won't be going

I think the dinosaurs would scare him more than the jungle animals at Rainforest LOL.
