The second year we used the DDP, we had problems with restaurants charging meals back to our room, instead of taking them off the DDP. Ever since then, we never leave a cc on file. I always take Disney gift cards down there to pay for anything I want. I love coming home to a zero balance on my credit card and money left over on the gift card to use for another trip.

I also like that every time I use the gift card the receipt shows the amount used and the new total. If an error is made I can catch it right there at the store/restaurant.
