Tough call. Atmosphere better at CRT, but wait getting in is a bit of a problem. They stop everyone to take pictures with Cinderella, so it gets backed up. On the plus side, DD closed her eyes for picture last time and they let her go back downstairs to take it again until she opened them. Cinderella was very patient and a sweet heart.
1900 had better food (but not that big a difference, as both were good), but I wasn't as relaxed there for some reason.
Your DD will get more princesses at CRT.
