I just want to warn you, we were there on an off week the parks werent busy, we didnt have any waits anywhere but every single time we went by Downtown Disney the TREX place was a MOB scene.I mean lines out the door and down the street. If they take ressies, I might risk it, but even then it looked like a place I will avoid for a while. We tried to get into the gift shop to see the "Build a Dino" which is a dino version of Build a Bear, and it was hard to even move. The place looked awesome, might be a bit scary for little ones.
Get a reservation!!!!! Oh, and it looked awesome inside, and the Build a Dino was adorable!
