I splurged for a hot stone massage at SSR in November. It was very pricy, but worth it, for a once in a (long) while treat.
I arrived with plenty of time until my appointment because I wanted to explore the amentities. The place was almost deserted, but I was greeted warmly by the CMs.
There was a problem with the stone warmer so I ended up waiting an extra half hour or so, but they were very up front and apologetic about it. I didn't mind, since I had plenty of time, but someone who was in a rush might have gotten peeved (they didn't offer to take anything off my bill, but it *may* have been because I was already getting a CM discount).
The therapist was great. I'm not someone who likes to talk during my treatments and after a few minutes of small talk, she seemed to sense my disinterest and remained quiet, except to ask every once in awhile if the temperature was okay and how I was feeling.
I loved it, despite the cost, it was totally worth it. They didn't rush me out of the amenities at all - in fact, they told me that I had use of them all day, so I briefly considered grabbing lunch at the SSR foodcourt and going back, but I decided against it.
