Say I made a 3 day reservation at SSR through one owner then found a different owner to rent me 1 additional day immediately following the first 3. Could I somehow combine these reservations or at least make it so I didn't have to switch rooms?
I believe they can be linked if they are for the same room category, but each of the owners would need to contact DVC to request they be linked. You might have to check-out and then in again as a formality, but shouldn't have to change rooms if they get linked.
My DH and I have separate memberships and I've linked a reservation that was made partially under each of our memberships. Everything has to be exactly the same.
If they are the same room type, you should easily be able to get them linked but if not, just ask at check in if they can make sure you don't have to move then go to the desk early on the change day and ask again when checking in the second time.So, I probably can't get them linked, but I can likely not have to switch rooms and just swing by the front desk to check in/out in the morning at worst? That I can handle.
