Don't know if this will sway your decision, but hubby and I were there last Jan (yes, the week of New Years) and went to T-Rex on a whim, NO reservations. The line was spilling out the door, it looked as if we would have to wait hours. We stood in the no reservations line, gave our name and we were seated in 15 minutes. I couldn't believe it. I am so glad we did not give up and leave, we almost did. It was the MOST FUN for all of us. The waiter was DJ (never will forget it--he said it was short for Dino Jockey). He took my 8 year old on a guided tour, took pictures all over the place then went to the Build A Dino (like Build a Bear) place with him. My son still talks about having the best time there. It really is something we all won't forget. Hubby and I split appetizers and DS had a kids meal and it was very good. Would really recommend it. And, if you can't get a reservation, just put your name in and let them seat you! Hope this helps!
