Also, note that some of the places where you charge things might not seem to be what they are on your itemized bill (however you wish to look at it). We were at the Food & Wine Festival once and liked a grapefruit wine so we bought a couple of bottles at the booth and had them sent to the front of the park for when we exited. We charged it to the room. When we got the bill, the vendor was not what we expected and were quite willing to ask for an explanation. Then we noticed the date and time and realized what had happened - the independent vendor was listed, nothing with "Disney World" or "Epcot" or "Food & Wine" on it. So, if you do charge, keep in mind of when and where it was.
