My best advice, is to continually, every other day, at least, check your account. On the TV in your room, there will be a channel that you can access that will show all of the charges made to your room/account. If there's ANY questions, clear it BEFORE you get off the ship! I've read horror stories of charges not intended that were months getting settled. We've been fortunate, we've only had this happen once, (in 5 cruises) but my husband had to go find the hostess who made the error, and have her clear it off the account. Ours wasn't that big of a deal, but sometimes they are. Don't sweat it, just be aware. Enjoy your trip!
