So to answer your question.
Roman Holiday was what most would call a gay bathhouse. They give you condoms at the front, there are communal play areas and private rooms. Those are 18+, require ID, may require a "membership," etc. In Vegas, the bathhouses are Entourage, Hawks and Kumi. I find that many straight types -- guys I seem to attract -- do not like going there because of the ID or "membership" requirements. On the flip side, you can do whatever sexually and know the other patrons are cool with that. They're also relatively inexpensive.
The hotel spas, as others have mentioned, typically require a service ($100-200 but grant entry for patrons who go that route. Some may offer day passes for just the facilities but even those can be $75-100+. Some only offer day passes to hotel guest. I was just at Mandalay and you could only get in with a service. I've been there in the past when it's only open to hotel guests. And other times when it was open. The consensus is Qua and Mandalay have more gay or curious patrons. I personally have found Qua to have some racially intolerant patrons so there's that.
Korean spas are segregated by gender. They have co-ed areas where everyone wears shorts. Otherwise you need to be nude. They do not allow people to wear trunks etc. However in Korea, the spa experience is a family one. Children may be seen there. However, these establishments have been largely co-opted by gay men and most Koreans avoid Korean spas. Imperial Spa in Vegas is a Korean spa. They have signs prohibiting inappropriate behavior and have known to toss or call the cops on violators. I have found patrons at Korean spas (to clarify, the non-Asian patrons) are racially intolerant of Asians. I know, it's ironic that Koreans are treated like shit at Korean spas but that a big part of the gay community (i.e. no Asians, no Blacks).
If I make a real connection with someone at a spa, I'll take it up to my room.
You can DM me for more info.
