I've never been to 'Paradise' but Stuttgart is quite a nice town to visit if you have reason to. Not as well appointed as the bigger cities, but plenty of pussy right in the centre (or for FKs, as is usually the case, you mostly have to travel out a little bit.) The south of Germany is much more laid back than the north. Prices in the shops are quite cheap compared to the UK. Excellent transport facilities etc. I suppose it is mostly the ratio of flight price vs amount of facilities that tends people towards the bigger hubs.
If you are stuck in Switzerland (gold-plated credit-card pussyland) and need to exercise your dong without having to mortgage your house, there's excellent trains that run to Stuttgart.
I maybe have to correct myself, sorry. I was trying to recall the name of the FKK I visited in Echterdingen, which is a southern suburb of Frankfurt and I think may indeed have been "Paradise." I def went to Sakura, another FKK in the vicinity and reviewed it. I think I preferred it to Paradise.
A bit like an enormous spa. The reception is a bit like a 5 star hotel. The atmosphere is that they treat you as if you are loaded for coming to the joint, posh in other words. But at least you do get the feeling that everything is completely above board. Tour available (the place is enormous). Various areas for shagging or just relaxing without getting hassled. The girls wandering around stark bollock naked mostly. They don't hassle unless you make eye contact but if you do there is the typical German lack of subtlety. There is no natural chit-chat as far as I was concerned: they are in competition to nab as much prey as possible. Food (fairly good quality) is rolled out at intervals.
Lookswise most of the women are ok, some very nice looking. But at these prices and razzamatazz I would really like much, much more than ok. The nudity is not particularly sensual to my mind. They wander around a bit like people on a regular nudist beach without much eroticism. I rather felt that personalities had been left at the door when they clocked on for work. (I'm not denying that if you are more used to German culture and can speak German naturally, you could probably dig much deeper.)
I eventually picked what seemed the least worst bet. Having got there and gone through such a rigmaorole, leaving without a shag would be pretty pointless. It was ok, nothing special. I think she had a buzzer or something to say when the time was up, and it was concluded with crisp German politeness. At the desk on the way out they checked that everything was ok. Left and jumped the S-train to Hauptbahnhof (central station) to chance my luck among the more "free range" cheap-as-chips Eros joints.https://www.ukpunting.com/index.php?topic=4392.msg65405#msg65405
I know that FKK fans will pour scorn on Eros clubs, that's their choice. I am not so much disillusioned about the cash as the amount of time involved in pissing about (getting there, going through all the niceties). OK value if you like the style and maybe want to stay there all day, enjoying the fanny and the food. I personally found them a bit boring and the attitude of the girls within too narrow a range (little element of "discovery"). For Eros centres you can just roll in, for instance Stuttgart has a fucking enormous one, you can almost get lost there on all the floors (dozens of rooms, each with a different girl in the doorway) nip in before elevenses then do another couple after lunch, all within walking distance of pubs, restaurants, tourist attractions, and the cost is barely noticeable.
