Thanks, tink, for the advice.
I'm a little slow-moving this morning, trying to get over the Panthers' devestating loss last night. I called AAA, and they were true-to-form...they knew nothing about the certificates, but I truly did not expect them to. I called the Residence Inn Lake Buena Vista, and the reservationist didn't have a clue about these certificates, and did not know who to call and ask. She was quite honest, though, and told me "I don't have a clue." Anyway, after re-reading the back of the certificate, I called the toll-free number listed(the one beside the statement "Reservations MUST be made in advance by calling...") I know, I know...Where's my sign? Anyway, this number is the Marriott chain booking number, and I was only quoted rack-rate once I told her I had a Bonus Bucks coupon(but she did know what they were). I checked room rates for 2 different weekends(one in Feb. and one in May), and the rates are: $114 for a studio, $130 for a 1-bedroom, and $200 for a 2-bedroom suite, NOT including tax. I was hoping for better room rates so DH and I could take a quick trip out of the cold...I think I can do better in one of Disney's resorts with an AP rate. Has anyone else tried booking using these certificates?
