Honestly, we were sooooo disappointed in the Crystal Palace and will never go back again for lunch or dinner. I would possibly consider breakfast but the lunch food was terrible - the worst food we had all week at a TS meal. Also, there were problems with Tigger - he kept skipping tables and then when we tried to talk to the handler to get him to come back the handler was rude and Tigger was rude - we could even hear him talking - at one point when another family was getting pictures he said was mad about how many they were taking and said audibly "Come on man!" I've never heard of anyone else having this problem but there were several tables near us upset as well.
If your kids REALLY want to see the Pooh characters then go for it - but if you are hoping for a good meal I would go somewhere else.
