there is a grass area at the club that will accomodate several tents, only 20 yards from the club door!
There are 'proper' sites about 2 miles away.
Also there is a travel inn 5 min drive and loads of guest houses and hotels along the seafront opposite the club.

there will be a few spitfires there to snap at the F16 heels!
