I used to come here all the time with my promoter friend, who happened to be the first friend I had in Vegas.
Rain goes for a specialized crowd and doesn't really show itself off like other nightclubs such as XS and Marquee and Tao do. You do get headlining DJs like Dash Berlin and Rusko every Saturday night, and the music primarily is either Latin on Fridays or Electronic Dance Music on Saturdays. However, this club DOES get packed, and they can pull in their people without having to be as public.
I would say that the people that come in here are much more well adjusted than anywhere else. I have NEVER seen anyone get kicked out or get into a fight here. Not in a single full year of coming here. A lot of people from Europe, a lot of the older grown-up raver types. Civility-wise, I say they tie with the folks that go to XS in terms of keeping the peace.
During the residency of Paul Oakenfield, they had acrobats and performers hanging upside down on the ceilings and swinging on these circus monkey-bar things after midnight. They got these robot guys with diving helmets walking around on stilts handing you glowsticks and high-fives. And they got these dudes in skin-tight bright colored body suits flopping around like worms or fish on the stage.
Also on Saturdays you get the Party Harder Stamp, which allows you free entry into the neighboring Ghost Bar and more rowdier Moon Nightclub.
