If you are in Ixtapa, most of the action you want is in Zihuatanejo. It's a short drive away, like a bedroom community for local residents who mostly work in Ixtapa. Like all cities, the brothels and massage parlors change addresses frequently. Here is a forum report from ArtistType. "There is action in zihuatenejo. A local hotel in the centro has onsite action for roughly $70. If you venture out to the gritty centro streets around 9ish you will find a street with few bars that has on site action for roughly $35/40. Zihuat can be very sleazy from what I saw. If you like the Senor Frogs crowd Ixtapa is the place to be. "
