If you had one day to spend either at Animal Kingdom or MGM-Disney Studios, with a 5 yr old and a 3 yr old (girls), which would you pick? We are first timers and have to choose one or the other for our one day we don't have planned. I don't want to try to do both in one day with our young princesses. I am planning on them being worn out for the day by 3:00 or 4:00pm. Thanks for any replies!
