I am having the same issue. It doesn't matter what dates (Sept, Dec), what type of accommodations (value, mod, deluxe, or villa), with a special promotion (free dining, % off, normal no discounts) it tells me the same thing. No rooms available. I have even tried using a different web browser thinking that was the problem....nope...tells me the same thing on Internet Explorer and Chrome..
They are indeed, updating! I called in a moment of panic because we need a room for next Mon-Wed. CM said the system was down and to call back in a couple of hours. Online ressies are down as well.
Thank goodness! lol
Not sure if it's connected, but I booked a room last week, never got a confirmation email, called twice to request one, and still haven't received anything.
