I'm planning on hitting up Air BnB, but it's not clear whether transportation will be straightforward. I'll be renting a car, and I might not be the only one, so we might coordinate carpools to get people to and from the venue.
King rooms at Hampton Inn are $93/night when part of a group reservation. King with sofabed and two queens are also available. There's lots of fine print I still need to go through though, and there would be a strong cutoff date ("All rooms must be reserved by 14 Jun 2016").
