I have rented pts for 12/18/07 - 12/20/07. But I'm still looking for more days, and they are probably going to overlap, if I'm successful in securing a existing reservation from someone for around that time period. Is it alright to have 2 DVC reservations in my name, or should I put one in my daughter's (20 yrs. old) or does she need to be 21? Thanks.
