I don't know about BCV, but we were at BWV this past year and Santa arrived in the lobby a couple of evenings prior to Christmas. We left for home either on the 22nd or 23rd and he was there the night before our departure. I remember there was a schedule posted in the Winter Vacation Magic as to when he would be at the resorts, but I don't remember if it was all of them.
He is at DD during the day and evenings.
