I would also recommend asking for a print out of charges periodically as you go thourhg your stay - like every couple of days or so, as well as the night before you check out. That way you can resolve any problems before they charge your card. This was suggested to us by the staff at the resort desk during our 1999 stay at ASMo. It was a good idea we did, too, because on our first night, we had dinner at the Concourse Steakhouse, and two dinners ended up being charged to our room - the amounts weren't the same, so it looked like they had mistakenly charged another customer's dinner to our room, as well as our dinner. If you check you statement of room charges, any problems like this can be brought to the attention of the front desk as soon as possible, and easily resolved.
