I've been going to Daytona for 12 years running now. I stay with a friend of mine in the West Lot in his motor home. If you can do it, it's a great time. Just in the west lot alone there are over 900 camping spaces, used to be more but they did some site improvements prior to this years 500. (Drainage, interior road paving, etc...) There is water available and pump service also. (I believe it's $35) The past couple of years we rented a Johny-On-The-Spot for $80 for the duration of the time you're there. We just put a pad lock on it so no one else uses it. I've been on the grass for driver introductions, drove around the track with a Daytona Beach cop, I'm a retired cop, so we just told him we were law enforcement from NJ and he said, "hop in". That was a blast, it was on a Friday night before they started running the truck races at night. So, with all that said, if you can get there sometime, do it!
