Does anybody have any recent experience with booking MGM properties in Vegas, specifically Mandalay Bay? I've gone through the Hyatt site and they seem to only offer one rate and two rooms (the Deluxe King and ADA room) and no suites of any kind, even though they do show on the Mandalay Bay website itself. I have a couple of conferences early next year that I'm already booking for, and I'd like to avoid any issues with booking through MGM directly and find out that Hyatt won't give me the stay credit. A call to the Diamond line shows the same thing, with them just telling me that they can see the same rooms as on the site, and they can't book any suites or any other type of room, and that I should call / visit the Mandalay Bay site directly. Any thoughts?
