I think I heard last week there may still be a few rooms available Ricardo. But yeah, if you want one of the SW.com "blocked off" rooms, you have to register through the GenCon site for a pass, and then they'll give you the hotel code and info you need to try and find a room. Most of the real close ones (and more expensive ones) I think sold out pretty quickly, but I'm sure there's still some in the outlying areas not too far away that can still be had for a decent price. I can't recall, but I think that some of the cheaper ones were a little under $100 a night.
Hang on just a second, and I'll see if I can login and find out if there's anything still available, and for how much...
