Campgrounds near speedway still have vacancies for weekend.

With just 11 days to go until the Coke Zero 400 race at Daytona International Speedway in Florida, a local campground owner remains hopeful he will sell out the weekend, but may be biting his nails as race fans wait until the last minute to reserve a campsite.

Brian Dwyer runs three campgrounds with 800 sites in Daytona Beach. He expects two of his full-service KOA campgrounds to be 80 percent or 85 percent full for the race. But his other campground, the Racetrack RV Park across from turns 3 and 4 at the track, is not looking so good, the Daytona Beach News-Journal reported.

That park, which is opened only for special events and has water and electrical hookups only, will be lucky to be half-filled.

“We used to sell out and that doesn’t happen anymore,” Dwyer said.

Still, the summer is a slow time for North Florida campgrounds and any added boost from events is appreciated, Dwyer said.

This year’s 400 race is on a Saturday while the Fourth of July falls on the previous Wednesday.

Last year, the race was held on the Saturday two days before Independence Day — a perfect chance for race fans to schedule a three-day vacation weekend, area hoteliers said.
