A day or 2 at a club or a resort on holiday

In a couple of weeks I am going on a trip through England and was wondering if there are any clubs I could visit for a day or 2, I will be travelling from Hastings up to Sunderland and was hoping to break the trip with my first ever visit to a nudist club or resort on the way.
I e-mailed a club in Nottingham about a short visit and was told they only allow members to visit but am hoping the collective on here might know of any that are more welcoming to short visit naturists anywhere south of Sunderland.

Thanks, Kevin
