There is another right on the city beach, called the Danaos in Nea Hora. This is a good place to stay if your looking for women, pro's or not. There are always a few girls staying there that are pro's. The best bet is to stay there, then visit the clubs and see who you run into from the hotel. From there some very convenient arrangements can be made.
Prices are also about the same.
A drink for a girl in a bar costs from 1,000 to 5,000 Drachmae. A few of the real nightclubs will cater to tourists during normal hours, then open up again later. The pro's will go to these places and work until 6 or 7 o'clock in the morning, and things can get really wild. I personally don't care if a woman is a pro or not, but I find that a lot of the pro's like to go out and have a good time.
