That is exactly the ages that I took my 2 boys. We had a great time. We spent a few hours in the park in the morning and then went back to the hotel after lunch everyday and took a nap, then back again for dinner and the night time show...I actually had less problems with the kids whining, etc then when we were home. The only thing I did not expect was how afraid of the characters my 2 year old was. Therefore we only did 1 character meal and everything was ok.
