I've been to one in the UK and a few in Europe. The UK ones are quite different because of the weather, not as hot and usually always cloudy! But its definitely an experience and one i think most people should try at least once. You don't have to go all the way straight away, try topless or something for starters. I found it a very liberating and freeing experience. Though you will have to be prepared for people staring or looking, and occasionally coming over to chat. It's usually always friendly though, as long as you're comfortable with people looking at you in the obvious areas! It never becomes inappropriate though, I've been asked a few times if I want help with lotion etc or if they can have a feel, but nothing more than that really. If you're confident about yourselves you should definitely give it a try
