I believe camping for NH is for camper only and I think they charge you money (I read somewhere on their site that it is $100/camper, but I am not sure). If your dad is interested, he can be a corner worker, he can get vouchers for you for future events -> http://www.tonystrackdays.com/category/101/corner-working.htm
I guess it is up to you guys regarding lodging and transport, since we are all doing the same event. Either way, I don’t mind splitting the van or the room to cut cost. The Ryder panel van should fit 3 bikes, I just need to find out if there are enough anchor points for tie downs -> http://reservations.ryder.com/StartContent/VehicleInformation.aspx?param=Panel%20Van
