We frequently combine cash nights with points for a number of reasons. I've always had DVC link the reservations so we know we won't have to switch rooms. This last month we signed up for magical express and they sent us two sets of bag tags, one for each reservation. I emailed into DVC asking to confirm that our reservations were linked and received a response that says they noted on the reservation but are not guaranteed. Their new policy is to only link if two different memberships are used. Does anyone know about this? Seems infinitely short sighted.
