Actually, having never been to the green door, I have no firsthand knowlege.  I can, however, relate from "swingers sites" that it really is terrible.  Hardly ever any couples, small, smelly, dark, sleezy etc.  As a matter of fact, there are a few other places right by there, and from what the sites say, not much better.  I would suggest you stay away.  As Nikki and I posted, the Red Rooster for a single person (male or female) is really hit or miss.  Although it can be interesting, there are couples areas only where a single person can't go.  They are pretty strict about this.  I have never gone "solo", and can tell you that the couples areas are rather voyeuristic, and there is generally not much there that would interest people.  They do have a website with pictures.  I forgot the site address, but a simple search will direct you there.  Trust me the pictures are usually better than what you will find there
