We are planning our WDW trip. It is going to be me, DH, DS(6), DS(3) and my parents for 7 nights. My brother wants to come too, but he can't get the entire time off from work. He was thinking about flying in later and only staying a couple nights. We are planning on doing a 2 bedroom villa at Old Key West, so we have plenty of room to add him. He would just stay on the couch. Could we just add him when we got there and take him off when we leaves? I would hate for him to have to get his own room, when our room has the space. Thanks.
