My two kids were always asking for all kinds of stuff while at the parks. "Daddy, can I have popcorn; Daddy, can I have a ice cream?" All that adds up, right? So I decided to come up with "daily coupons" for the kids. These are just some "coupons" that I created at home using MS Word with some Disney pictures on them that said something like "Good for one Popcorn" or Good for one snack and I would put a price limit on each coupon. Each day of the trip I would give each kid 3 coupons a piece and once they used those up, that would be it. (Of course the "main meals" and the occasional mid-day snack did not count) Boy what a change it made! First of all I could better budget for the trip by knowing I would not be spending more than "X" amount on misc snacks during the day. Second it introduces the kids to handling money/trade. Third it gives the kids more responsibility. Aside from the dollar amount limit, the only rule we followed was no snacks right before going to a meal or b4 entering a building were they would need to throw it away. Aside from that, I did not place any restrictions. If they wanted to use all the snacks first thing in the morning, well that was their business. They could even save the coupons for the next day if they wanted or "sell them back" to dad/mom for 75 cents on the dollar. Give it a try and see what happens.
