Top Shelf it you haven't signed up for the CRT membership you should to get full access to all the info on CRT.
Do a search on Jaco. There's lots of info on P4P available.
JACO is about an 4000K cab ride south of Los Suenos. Less than 10min ride
Daytime activities in Los Suenos area:
1) World class billfishing. Yes it's expensive but worth it IMO. I shared boats with others that i've met right there at the dock in the morning.
Costa rica dreams or Maverick Yachts the top two charter outfits.
2) There are several Canopy/zipline Tours located close by.
3) ATV tours.
4) Nice Golf course there at Los Suenos
5) Surfing (jaco)
6) Casinos
The Mariott is very strict on bringing girls in.
Beatle Bar is the epicenter of night time P4P in Jaco. I would cab it over and back. Renting a car is not worth the hassle and worry.
Some Beatle Bar girls will take you back to their apartments or cabinas in Jaco. Don't tell them your staying at Los Suenos though. Just tell them your at the Best Western in Jaco and they don't allow chicas. If you mention that you stay at Los Suenos you will be considered "Muy Rico" Very Rich.
$100 is the normal asking price at BB. You can and should negotiate a lower rate, and or more time. $50-$80 seems to be what they will come down to.
Don't drink and drive if you rent a car.
The cops frequently have checkpoints.
You will have fun!
