Ah, I gotchya now. You want to SELL a BRG night.
Wasn't clarified before. Sounded like you FREE nights for us, not for you.

"Free nights available"= I BRGed at a bunch of hotels and don't plan on using them. Therefore, I am offering them out.
"Selling Free nights" (i.e. Hyatt nights, Hilton nights)= I earned a free night by opening up a credit card and am willing to sell it to you.
Atleast, that's what the normal human intellect would think.
