Just in case you don't already know about it, there's a fairly active forum on the Gen Con site (main page, scroll down to the bottom, click on "community", then make yourself an account if you don't already have one) for just this sort of thing.
Once you're in to the community page, click on "forum" then look for a block of 3 sub-forums (you might have to scroll down just a bit) - one is general info for 2013, the next is events for 2013, and the third is travel, housing and dining; and that's the one you want.
