Here's a more fulsome review then from a post I did on an AMS focused forum:
So for those that are familiar with Amsterdam, Yin Yang is a 2 hour train ride from Amsterdam Central Station in the town of Roermond. It's laid out like a large mansion with some small grounds, indoor spa facilities and an outdoor pool, steam room and such. It's in the countryside and the ride up in the taxi took me by some horse grounds which were neat. Very upscale locale, albeit the experience, was a bit awkward for me.
Sauna Clubs, whether in Germany where they're most famous, or other parts of Europe are apparently the same. Upfront fee for admittance (€50-60 usually) which includes a mediocre buffet and access to the facilities - includes beers but in this case no hard liquor. The place is filled with girls who operate as indies there, prices start incredibly low, around €50 per 30 mins but pick the wrong girl and it can be incredibly mechanical and significant upselling can be part of the experience, although not nearly as bad potentially as with the "Window Girls" of the Red Light District.
When I arrived, it was about 4PM on a Friday, went through a very smooth process, got my locker and my robe and was eager to get some relaxing in after a bunch of hectic work days.. I arrived and it was a shocker, the male-to-female ratio was nearly 20-to-1 in my "favour" which made it somewhat awkward .. I felt a bit like a deer in headlights.. The girls were clearly not getting much business so got a bit aggressive .. Ended up retreating to the saunas a few times.. Spoke with quite a few girls and regulars, apparently the ratio swap is very rare. That said, I spent some time with Romanian Christina - very sweet and at €50 per half hour for full GFE was very nice. Ended up going for 1 hour nonstop, I had already had a session earlier in the and she really got into it so no problem being turned on.. But just couldn't finish!
Spent some time relaxing, retreated to the Men's lounge to do some work and then tried to see a blonde, maybe Russian, she said maybe later so that didn't happen.. Never been turned down by a girl before, but she was one of the few that were constantly busy all day. Part of me likes the colder more aloof looking girls sometimes..
In an effort to make sure I finished and finished strong, I then opted for a 20-something brunette and 18 y/o blonde duo, again for an hour, they did upsell €50 each for interactive (eating each other out, etc) but a duo with also otherwise full GFE for €200 (€300 total for interactive) for an hour is also very good value.
I would say from my experience it's like a RLD literally inside a spa-type building so that's kind of amusing. The grounds were very nice but smaller than anyone would think from the pictures. It was an experience and if it wasn't so far to get to I'd think about it more serously.
This trip though has made me think about sex (which in Europe, is relatively cheap and abundant) and companionship (more expensive but sometimes you get lucky) and what each service - RLD, Saunaclub, Private In/Outcall - seems to provide
PS: I would also add that I was the only Asian guy there and most of the male clientele were in thei 40s++ although there were like a handful of young guys. The girls kept calling me "China" and we're surprised when I spoke perfect North American English. It was both amusing and annoying.. I was apparently relaxed and performing well enough though that the girls commented on it, which I was amused by, as to them I was "small (5'7") but strong!"
