I went there with my partner on our anniversary, to introduce him to the joys of hot-tubbing. The staff was not only helpful but outright friendly and sweet -- they helped us pick the right service for our money, and even gave us a discount when the jets were slow in turning on!
The room itself was spotless, private, and had a small bed in it; a privelege, I discovered, of the VIP rooms. I recommend this over hotel rooms for the sexually adventurous. The look and feel of the room was also rather enchanting, dim lighting and well-arranged decor. There's a TV and a radio, but who would watch TV in here?
The rental cost about $40 for an hour's enjoyment. The most lovely and surprising feature here -- something I hadn't seen in the hot-tub places I used to frequent in California -- was the water system in the ceiling: you turn a lever in the wall, and a light, cool mist sprays out from above, which in the hot water is extremely pleasant.
It was a beautiful experience, all in all, and the only disadvantage was the cost. Which is worth it, at least every once in a while.
