For the first time in October we will be sharing a 2 bedroom at VWL with another family (my in-laws!). When we check in, will each family be able to give a credit card so we can each charge our purchases back to the room? Or would all of the charges go on one account which we would have to divvy up between us? We love the convenience of not having to carry cash, but I don't want it to get too confusing either.
