BRP How will I know?

[buzzgirls&dad]

We booked a AAA ressie @ BWV and wanted to add a day. The only way to do that was to do BRP for our last two nights so we didn't have to pay rack rate. My question to those in the know is how will I know if my rate does go lower. Do I get an e-mail, do I have to call like the old program, how do I know my ressie wasn't missed? TIA
