Unfortunately I think you can only do that online.
I have a 91 point a year account and I think I figured out in red (prime) season it would normally get me about 6 nights in a 1 bedroom. In lower seasons I get more bang for my buck.
Their instant exchange program I booked a week in cabo in december for 91 points plus exchange fee..........
Heres some other info for you
