I guess my only real advice would be to take it slow, and start with the basics - like Small World - things that move, but REALLY slowly and no great suprises. Also, spend a lot of time at ToonTown Fair! I didn't see ANY kids who were afraid of the stuff there! My daughter just kept talking about how messy Mickey's house was! When we started on this trip, we decided that we were just going to try and find joy where Grace (dd) found it. And that really worked. She was thrilled just riding the bus, swimming, looking at stuff, the parades, etc. She wasn't old enough to hate waiting on line, because we were there with her, pretending like the line was a ride too. At this age, I think they can really be made to believe anything. And if they think that you like the sweltering heat and think it's fun to have your clothes stick to you, then they'll think it's fun too. I would definately suggest a "Mister Fan" - she had MORE FUN with that thing! Other than that, just try and have a great time. Incidentally, we took our daughter when she was 17 months old the first time too, and she was a dream too, but you will see SUCH a huge difference in how they interract with everything at this age - especially with the characters. She absolutely loved them - and honestly believes that Mickey, like Santa, can be in 3 places at once! Have a great trip.
