I tried to do this yesterday, and they said no (in fact, this CM gave me a big guilty speech about how the BRP was a perk for people who have APs already, not a room discount...) I tried again today, and the CM told me what was available, and I booked 2 rooms at AKL from Jan 25-Feb 1 for $109 per night. Woohoo! After she gave me my confirmation, she helped me to buy my pass. It was well worth the $420 for the pass, especially because I got 2 rooms. Be persistant, and you may find someone who will do it for you. I was very clear and said I didn't want to risk buying the pass, and find nothing available.
Good Luck!
