I also remember Mickey Mania having more visual clue/questions - like a very distorted view of a character that they brought more and more in tofocus and you had to be the first to guess who it was - stuff like that. WWTBAM was more like the TV show (phone a friend was ask the panel).
MM had a panel of players at a time - each team a child and adult.
the winners received a medal to wear.
WWTBAM could be a sole contestant though if under a certain age you had to have an adult with you to claim the prize since it was real - stateroom credit up to a cruise if you won it all
