One of my daughters and I arrive at night and will check into our DVC reservation. The next morning, my brother and neice arrive, and about an hour after that my husband and other two kids arrive. Do I need to be "home" when they all get in? I was hoping to not have to wait around for them all and they could meet us in the park. Is it possible for check-in to hold their keys? Or is this asking for trouble for everyone? Thanks!
