Does anyone know if it is allowable to book two rooms at the same stay? We need to accommodate 15 people and trying to figure the best option.
I was just able to book 3 Value rooms at AKL. I needed the names and addresses of all party members. I booked at the 11 month mark on the exact day.

Yes, you just give them a name of a "lead" in the other room. For me the rooms are generally in my name and my daughter's name. Both rooms can't be in your name (at least they told me that). They will now put both rooms under the same confirmation number to help ensure that the rooms are in the same location.
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.
