You can, but be aware of one thing. For whatever reason, WDW Travel is recorded on most prepaid cards as a transaction requiring a 20% holdback. Typically, when you go to a restaurant, they will put a hold on a credit (or debit) card for 20% more (to cover tip, etc). The WDW Travel transaction does the same thing (I don;t know why). So be sure that you have the amount you want to charge plus 20% available on the card, otherwise it will likely decline and you'll have to choose a lesser amount to pay. The 20% should release by the next business day.
