I am looking into renting DVC points for a stay for my daughter and her college roomates during their spring break or at the end of their spring semester (pending availability). These girls are all 18-19 years old. Would I need to be present during their check-in or would they be able to check in by themselves if I put the reservations in their names? Also, when renting DVC points, is there an additional fee per adult after 2 adults?
