I stayed at Tewkesbury for a week back in August. The site was full most nights which did mean waiting for the shower in the morning. There does seem to be a lack of showers given the size of the site although they were kept clean.  The warden was helpful when I had a problem with my car.  Other caravanners were extremely helpful as this was the first time I had towed my van with this vehicle and only the second time of towing!! They helped me setup when I got a bit muddled and when packing up assisted with taking down my awning and hitching. I think I would only get get that support on a Club site.  Plenty of things to do around the area whether it is a long walk with the dogs or a trip to Gloucester, Cheltenham or any of the other Cotswold villages. I will definitely be going there again but will try to arrive for 12 to get the best pitches as struggled to get my van level.
