Been there, done that.
Most of the time, I either go home and sleep in my own bed, as its only a 1hr to 1-1/2 hr drive from Rockingham, Piedmont, Farmington, and Mooresville... still cheaper to drive than get a hotel. Kinston's much further, so the last two years I've skipped bracket raced locally on Saturday, and just roll out early Sunday to go into eliminations with no time trials. I'll "tent it" on occasion, and the other races I'm typically splitting the hotel rooms with Myron and/or Terry, or crashing at Hotel Bolton. Last year, I ran 58 races, and my total lodging costs were $890.05. Nuttin' fancy here!
