I am thinking of visiting Heathrow Kestrel nudist spa during the day without my wife. She is not into it.

Does anybody know what's going on there if you are a single? Is there anything else going on except having a drink and enjoy the pool? Are there any nude couples during the day except single men? Can singles watch when couples have fun in the play rooms without being invited to participate?

It's a long trip and I want to be sure that I will see something different than single men enjoying the pool.

Thanks
