I recommend getting a Disney Gift card, a small credit card type thing you carry on a provided wrist lanyard. You pre -load it with either cash or via credit card then when purchasing food they just scan the card, the cost is deducted and you get a receipt telling you have much you have left. Saves time, prevents you from ending up with several pounds of pocket change and it's a great way to discipline your budget. Don't want to spend more than $200? Load that much and you can't go over.
