Unless your into motorcycles I wouldn't recommend any campground close to Daytona Beach on those dates. We have Bike Week here March 7 thru March 16. The campgrounds are usually packed and the area is swarming with multiple thousands of motorcycles. The closest nice campground to Deland that I am aware of is Orange City Rv Resort (sunresorts .com). I have not been there, but I have good reports. But even there I would call ahead for reservations. If you need further details on the area let me know. January issue of Trailer Life had a nice write up on DeLeon Springs State Park, but no camping available there.
