I think I may have suggested this one before.So sorry if I have,try Riverside CP at Stratford,underfloor heated toilet block,boat taxi into town,pleasant walk if you want it into town club on site,also bowling club with bar at entrance and good pub with food in the village.You will need to book early as it is popular especially at bank holidays,dont book as rally only as group caravanning together otherwise you could end up on rally field without EHU also Margaret would require copy of an exemption certificate.
