Was in Vegas earlier this month.
Unfortunately Mandalay was closed so I'm looking forward to hearing the report.
Stayed at the Luxor during a ballroom dancing championship so there were a lot of dudes cruising, though not really my type. In January Vegas has a ton of gay athletes and later porn stars in town so it's quite a month.
Luxor spa was unattended. I went in after my workout to wash my hands and no one stopped me. Looked fairly empty.
Did make it to Imperial spa and had a miserable time. The "no Asians" crowd was their in full force: a white couple left shortly after I arrived; many guys would leave whenever I entered a steam room (keep in mind I did nothing but find an empty spot to sit down -- no cruising, no leering); and one balding and fat asshole kept doing it I actually called him out on it.
I eventually felt pushed out of the space and sat on the couch and killed time until I met my girlfriend upstairs.
Really nasty behavior that I've only experienced at Qua and a few Korean spas in LA before.
