Take your Vitamins

I was there for the first time  a month ago and plan to return in January......I spend 10 days in San Jose and Jaco beach so my advise comes from a newbie in Costa Rica but addicted to latinas and mongering in general. So here are a few pointers about SJ

San Jose has lots of indies action 24 / 7 - ground zero is the Del Rey with many bars/clubs nearby - the area is knonwed as "gringo Grunch" there is no need for an agency whasoever- If you stay at the del Rey you can pick from 100's of beautiful latinas (ticas(minority), colombianas, dominicanas, nicaraguense etc) downstairs in the casino and take them upstairs to your room.  I highly recommend you stay at or visit Sportsmen Lodge you cannot go wrong there especially if it's your first time in costa rica http://www.sportsmenscr.com/  SL is an elegant hotel/restaurant/bar in a quieter area a quarter mile away from the the gulch that let local  freelance chicas in, but no hardcore girls/hustlers inside it is more upscale than DelRey.

other places to check - Blue Marlin Bar, Key Largo (acroos from Del Rey), Monkey Bar.

if you speak Spanish you have even more options - below are primarily for locals
IDEM Bar, Calle 11, bet Avenidas 8 / 10. Clean, friendly, professionally managed, excellent quality control. 12-20 girls in the 6-10 range. Prices: 19000c upstairs rooms, 22000c hour downstairs a/c rooms. Open 3-12 Mon-Sat.

Pantera Rose, corner of Avenida 14 or 16 and Calle 9 (Just past the fork in Paseo de los Estudiantes.) About 9 or 10 blocks from HDR. Free entry & 1 drink with CRT card, or you get a Cover charge.
