We took the kids for their first trip to Disneyland, and of course they loved it. They're not thrill seekers so we didn't do any of "exciting" rides. They mainly did the "kiddie" rides, watched the shows and soaked in the Disney atmosphere. They loved each ride/show more than the previous one. Amazingly the lines didn't phase them. My son loved driving the car in autopia and my daughter loved the princess themed shows. We loved that the Disney characters roaming around the theme park actually stayed in character the whole time. From Gaston to Hook, from Aurora to the Beast.
