The best way to track your spending is to use your Disney resort room card as a charge card. At check-in you will be asked if you want this option. If you accept they will take your credit card and encode your room card with the information via their computer system. You can then use your room card in about 99.9% of WDW to charge everything. You can go to your front desk at anytime and ask for a print out of your charges. At check out they will give you a complete listing. If you choose express check out they will put this in an envelope and hang in on your door very early the day you are leaving. The maximum you can charge depends on your level of resort. For values it is $500.00, moderates it is $1,000.00 and deluxes $1,500.00. When you reach your maximum they will send the charge through to your credit card. We always use this option with the room card. This way you have less to worry about losing. If you do happen to lose your room card they will freeze it so no one can charge anything on it and issue you a new one.
