From what I've been hearing lately is that several of the surrounding hotels are now sold-out to VaporCon attendees.
I'm still thinking about going but it will definitely be last minute if I get to go. I don't have a room, but there's been some talk that there is some folks that will offer a spot on their hotel room floor for some loners that show up last minute (for a small fee), which is really cool.
Hell, I'd sleep in my truck for that matter, if someone would just let me use the shower once a day
