Not to add to things but if anyone is still looking for accommodations.... this place next door to the Townsend Gateway Inn has houses for rent at $200/night that supposedly sleep up to 16 people. http://talleyhoinn.com/the-inn.html
I looked into booking at the Gateway Inn and it seems that every room is booked. I snozed I lozed, yeah yeah, sadly I didn't know the wedding plans until after the first of the year and by that time Gateway was booked solid.
That said, I am looking at going down a bit early. I *MIGHT* do the Mid-O track day the Monday (18th) of that week but if I don't I might head down to Townsend instead. May be looking for a roommate to keep costs down. This place also has 2 bed, fridge and microwave rooms for $89/night and single small rooms for $69/night. Very reasonable and has good reviews.
