I called today to book my free nights at Mandalay Bay with my rewards. I had bonus nights and so I got two nights in June which was great, never stayed at Mandalay Bay and have always wanted to. The frustration was when I called, I was on hold for about 20 minutes and then the call disconnected. Call back, on hold another half hour and then disconnects and this continues, on hold a total of about three hours before I get to make my reservations. The good part is that I have 2 nights at the Flamingo and 2 nights at Mandalay Bay for a total of $66 bucks before taxes and anal probe fees.
