Yes, you can link two members' reservations for consecutive nights in the same resort and room category, and that will assure not having to change rooms. Usually, either member can call and have it done. You should make sure that both reservations name the same guests, preferably before linking them (but that can be done at time of linking if not already done but then you may need both to call). Note, if you link you won't need to change rooms but you may have do a mini check out and check in on the turnover day, closing out one account, opening another and getting new keys and a new parking pass if you have a car.
