I did something of a Southern house tour this week and stopped by all three currently-open houses.
Alien was interesting. I went through the Area 51 giftshop and restaurant and stopped in at the Cathouse. All three were much busier than I expected them to be on a late afternoon on a Monday. I went to the Cathouse and had a tour with the only available lady, sadly we didn't seem to have a vibe, though the price she quoted me for an hour GFE was a good deal. I decided to have a drink at the bar and get a feel for the place. Tina (?) was the bartender and being taught how things work; She was very friendly.
The place was kind of kitschy and fun, rooms seemed nice and the staff was friendly. I think they just need more girls, I believe at the moment there are three courtesans who would be in a lineup, the rest are appointment only. So I definitely see how a person could come in and no one would be available for a lineup.
