Unfavourable review

One afternoon at Abbey House Gardens, I was in the Belvedere, taking shelter from the wind and rain. I struck up a conversation with a couple who were about to get dressed.
Another man started talking about his experience of a well-known naturist facility, which the couple were thinking of travelling to in their camper-van. “They’d charge for the air you breathe, if they could,” he said. A lot of the people who go there (he told us) “are clothed swingers”, and the couple who run it aren’t naturists, which is “a contradiction in terms”. He recommended to the couple who were sitting with me that they should go to a different naturist facility (which is near the first one) instead, and gave them contact details.
Are there other naturist facilities which aren’t entirely what they purport to be, and are expensive for what they offer?
