A few years back we went on a family vacation to Walt Disney world in Florida. My wife came up with a marvelous idea to keep us from hearing the old "are we there yet, and how much further" questions all the way there. Before the trip, she went to the bank and got $40 in one dollar bills. She put 20 under each sun visor in view of the kids (we have 2). She told them that each time they asked any question like are we there yet or how much further, she would remove one dollar and put it into her pocket. When we arrived, any money left in the sun visor belonged to the child. It worked like a charm, each child got $20 spending money when we arrived!
