We just took our 14 month old son. He had a great time and enjoyed everything. From the kiddie pool at Blizzard Beach to the monorail, he had a blast. He flirted with the princesses and chased his brother around outside of space mountain. I underestimated how much he'd like the characters and parades. He liked Pirates of the Caribbean so much that we rode it three times. I doubt he'll remember a thing about the trip a year from now, but I will. And behavior-wise, he was the easiest of our children. He never fussed for a toy in a gift shop, got upset about not being tall enough for a ride, etc.
