I finally heard back from my TA!!!
Apparently, there are no values offered with my PIN, so I am now staying at CBR, with water view, for the same price I was paying at POP w/o FD. I must admit I am somewhat disappointed because I was looking forward to saving some $$$, but I guess I'll look at as I'm getting an upgrade in accommodations at no charge.
Now, I have to learn more about CBR.
