Yep! You just set it up when you check into your hotel. If you are using a credit card, there will be a hold put on the account. The default is $200 per day but you can ask for less. On our last trip, we set it for $50 per day to just allow for charging drinks at the pool, use at Volcano Bay and it was enough for us. Whatever is left over at the end of your trip is applied to your balance at check-out.
