Absolutely!! We just did this for our last trip a few weeks ago. It was great to use one card, then each night (or every other night) I would go to the front desk and get a copy of our existing charges. I believe they allow up to $1500.00 at a time, then they need to actually charge your card, then open the credit line again. We also used resort delivery for all our souveniers. This was really helpful in keeping down the load of things that we had to carry around the parks.
