hi harry we have used camping cheques several times they are good value and give you freedom to go where you like and know the cost. we have found the sites all very good but the dates for cc's very so check with the site guide happy holls
As we always go in the low season I always use camping cheques as they are super value. Have never had any trouble getting in any where. If a site is obviously popular a quick call on the mobile always gets a booking sorted out
