We've stayed at New Smyrna a few times and found the ride acceptable, but it's about 15 miles or so from Main St. The KOA on South Nova RD was a good spot too. About as close to downtown as anywhere else. If you don't need full hookups, the flea market has sites without any utilities and also has them with electric and water. That is where we stay most often. Best price and a straight shot to Main St and close to the track. Regardless of where you chose, pick up a map of the local area and use the back roads. The main roads are too crowded and it gets hot on the bike.
