If Vegas still considers COMDEX a key convention, prices will be higher.

First, I'll presume your not a "rated" player with MGM Mirage. If you were, I'd say call casino marketing and see if there is anything they can do.

If you really fixed on the place and can get a refundable reservation, you could go ahead and book. You can then watch the hotels web site, along with the various travel web sites (expeedia, orbitz, etc) for better deals.

COMDEX is not the show it used to be. As a result, it is not expected to draw as many people. If attendence looks like it will be low, the hotel might lower rates in an attempt to get more tourists that week. Again, I'd watch the rates closely, especially as the event gets closer.
