Each kid gets $50 in Disney $ at the start of a week-long trip. how and when they spend it is up to them. Any left over, we trade in for real $. Belle is 7, Buzz is 5, we've done this for 3 years. It works for us. I'm not above buying them something additional, but it helps them make decisions. I find it also helps my blood pressure when, say, Belle wants to get the Belle doll that looks suspiciously like the 35 Barbies she left at home. Personally, I think it's a huge waste of money, but not my money, so I shrug it off. P.S. She still plays with that doll daily, so I guess it was a good purchase, just not what I would have chosen!
