1: read the posts then ask.
2: don't expect to bring girls into the Intercontinental
3:You can walk from there to Metrocentro and in theory to the Zona Roja but since a taxi costs $1.59 why walk?
4:There are no bars with P4P girls like in the DR or CR. Maybe Caribena Morena but it is a MP and not a bar and Gina will ask you to leave eventually if you don't go with a girl.
5:There is Aqui Polancos with freelancers downstairs but there are also normal girls and girls there with boyfriends or husbands, hard to see or tell apart. It is in a tough area and it is a pretty tough place. You need a companion and good Spanish.
6: I would recommend against it for new arrivals, same as with Fenix which you will hear about now and then. Bad dumpy hardcore place. Really a MP type of operation.
About the Conquistador, at best the fee might be you pay for a double when you book vs. a single, really from talking to a guy who was a resident there for 5 months while his kid was in the hospital, he said anything goes as long as it is legal and doesn't make a racket, cause problems or complaints from other guests.
