A year to late but my favorite place to camp is, inside the Daytona Speedway.
The high bank track deflects the noise of the traffic that goes on 24 hours a day, making it very quiet at night. Wake up in the AM to the sound of Race Bikes on the track.
Go to the Daytona Speedway website for the many options for camping.
My last trip was on the pavement by Lake Lloyd. You get Water, Electric, and a feed for your TV with all the race action. Just outside the fence by that area are cheaper sites with electric, not sure about water. No sewer hookups but honey wagon comes around for a fee. Other options also some with no hookups.
Have fun, stay safe.
