We bought the magical moments games at WDW during a New Year's vacation when the children were (I think) 6 & 9. It's a hand held game with 16 different Disney-themed games to play (Cinderella Castle, Tower of Terror, Rock N Roller Coaster, Honey I Shrunk the Audience, Tough to be a Bug, Haunted Mansion, Spaceship Earth, Splash Mountain, Space Mountain, Big Thunder Mountain, Test Track, Dinosaur and others). Except for the Cinderella Castle game which is active when you buy it, each of the other games is activated when you walk by the associated attraction and aim the game at a designated spot. DS particularly liked the Small World game where the dolls try to attack you (apparently other people have interpreted it as the dolls trying to help you, but DS is convinced his version is right).
As much as the children enjoyed using it in longer lines, it was even more useful when we were waiting for our PSes, and they also enjoyed playing it in the car.
The cost was $19.99, I think, and it's a good idea to buy extra batteries at the time, since both of ours ran out of batteries before a week was up, and the batteries were much harder to find. They seem to only be available at WDW itself (almost every shop including resort shops) so if you don't have friends who could buy them in advance for you, you should stumble across them pretty quickly. It's a fun thing to put in a "going to Disney package" for a child. In a family with nice children one of the games might be sufficient, but let's just say I got two of them for our kids.
