Has anyone participated in one of these events? I’m curious about attending as I will be in Chicago this weekend. Any reviews or advice would be appreciated.

Sorry I can't help but now I'm curious to hear if others have info on it. Sounds like a fun time! Wish we had something like that in my area (Boston)

It was pretty much what you’d expect. 7 girls, 70 guys. Most of the girls are on TSE, so you can see them without the party element. I had fun, and got a BJ in the parking lot from a tiny Mexican girl, but I haven’t been back.

With exception of the TS parties in the early 2000s hosted by Allanah Starr in NY, every other one I've been to was not as advertised. They were all a huge sausage fest, meaning; as the other comment said 10X more guys than trans. Also most of the trans were more CDs or early in transition. Yes, some were in hotels with rooms to be rented out and others at established bars but it was more comparable to being at a strip club and being teased all night only to go home with blue balls. I've been to 4 or 5 in greater Chicago and they were all a waste of time to me. I can engage a specific provider and have a much better time.  

I been to a few of her parties. She used to have them at a bar in the East Village and cohosted with Gia Darling. Them she had them in midtown at a much larger venue. Actually she her when she first started out and she was very nice.
