I'm glad you love the Cotswolds. I live just outside Moreton in Marsh and its great. I would recommend Moreton CC site. Not that I've stayed there, a bit too close to home, although we were tempted to go there when we got a new van, just to try the van out. From what I've heard it's an excellent site and bear in mind it won the Calor Caravan Club Site of the Year award in December. From what I've seen from reception it appears well laid out and the staff are friendly. It's also within walking distance of Moreton itself, with its many tea rooms, pubs and its Tuesday market (be aware of handbag thieves). While you're visiting the Cotswolds, if you have a head for heights, you must go up Broadway Tower on a clear day, a marvellous site.
Enjoy youselves while you are visiting, you too Jo-Anne.
