We just went with a 20 month old. He was terrified of the dumbo type rides, but pretty much loved everything else. When my older son was 2 1/2 he was so scared on the Great Movie Ride and Spaceship Earth (when it gets pitch black at the end) and we didn't take him on Pirates or Haunted Mansion because we knew he would be scared. But the 20 month old went on all of those without any problem. He was too young to know to be scared. He was terrified of the characters though. He loved them from a distance, waved and said hi, but if he got within 5 feet he melted down.
