Did the family you rented to extend a stay with your rented night? I stayed at BWV last month with friends for 4 nights. One friend booked the first 3 nights and I booked the last night and linked her reservation so we would not have to move. She got a revised confirmation with all 4 nights, I never got a separate confirmation for the 1 night I booked. I confirmed with member services that everything was correct. When we checked in, it was treated as one 4 night stay in my friend's name, we did not have to get new keys for the last night.
