I am on a budget this year but cant do without a carpet. What I did was buy picnic blankets ( you can get them dirt this at tesco. 7pds and really really big! You can cut them to size and attach non-skidding material with velcro from pound store. So now I have a huge tunnel tent size carpet for less than 20pds!
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
