What's the name of this TV show?

I remember very little about the show itself, only that it was about this place that, for whatever reason, made people want to have sex with each other, it was like some sort of retreat or vacation spot? I only remember one episode really well, it was two coworkers, a guy and a woman, they hated each other. At each other's throat the whole time, they were there to figure out what makes the place so magical or whatever, I think for a competing company. They ended up having sex in the woods or watched someone have sex in the woods and then suddenly they were all into each other. The show came on late night, probably around midnight. Possibly Cinemax but not 100% on the channel. I am fairly confident the name of the show was only two words, sex hotel or something like that, something that caught your attention.
