Palm Springs was a refuge for theoretically closeted gay actors and others who worked in entertainment. It was a place that provided privacy, yet was also close enough to drive back to work. Having a pool in an enclosed back yard made it even simpler to avoid prying eyes (or cameras). And yet with celebrity came a level of visibility, so people who had the money would gravitate there too. And as a bonus, the mid-century modern style homes and furnishings gave a coherent look and feel to the place, where most of the time the weather fits the lifestyle.

I haven't seen Celluloid Closet for a long time, but that might be one to watch too.
Palm Springs is more of a queer resort than ever, these days, hosting special interest events, with a business environment that welcomes clothing optional venues.
