As a spa castle regular, I can tell you that AT TIMES, there is an orgy vibe in the steam room. I can also tell you (having gone recently) that now they randomly check the steam room at least twice an hour. There’s ample opportunity to have a little bit of fun, but in terms of it being a FULL BLOWN ORGY, nah.
If you live close by, it’s worth it, but if you live anything more than I’d say 45mins to an hour or way, you’d be better off going somewhere else.
And one last FYI, the real “action” goes on in the bathroom stalls or sometimes in the shower area nearest to the body scrub room.
