Word of warning tho... you will not be able to check in to both rooms unless there is someone with you (18yr or older) that is listed on the reservation as staying in the 2nd room.
We had (2) 2 bedrooms at BLT on our last trip all reserved with my Dad's
DVC points, but bc he wasn't staying in the 2nd room, CM would not let him check in to that room. It took some time before we figured out that I could check into that room since I was listed on that reservation. CM would not very helpful. Worst check in process ever.
