Hi, We are traveling on a family vacation this summer with my DH and our 5 kids. My mother and brother are also going with us. We are going to use the DXDP. My MIL and FIL are also joining us but they are not staying on Disney property and therefore will not be on the DP. They will be joining us for 3 character meals that they will be paying for. When we sit down, can we just tell the server that they will be paying OOP? I just don't want my cards/room charged for their meals. Is that possible? Thanks!
