It is impossible to build a web site that claims to cover all of Costa Rica, and leave off the adult activities available here. The biggest draws are our course prostitution and gambling. Prostitution is perfectly legal in Costa Rica.
Theoretically, those individuals who have registered as prostitutes are regularly examined by a doctor and carry ID cards. Not all go. Many of the ladies and gentlemen do not register. Some that have do not get regularly examined, and quite frankly, it would make little difference as many of the more dangerous STD's AIDS may not show up for months on any test.
The bottom line? Be real careful. While prostitution is legal in Costa Rica, procuring the prostitute or acting in any way as a go-between pimping is not. Again, the reality is different. There are also a number of hotels that while being perfectly legitimate with clean rooms and nice facilities, have bar areas or other areas where you can find anywhere from ladies waiting to be of service depending on the time of day.
One in particular has a really fine Sunday breakfast buffet. This is changing and there are now adult facilities in Jaco and on the eastern side of the country. There are also a ton of web sites promoting sex vacations, adult vacations, adult tours, escorted tours, exotic vacation, special tour guides.
These are simply businesses that hook up the prostitute and the client. The government does little to control this, probably as it is not a very visible form of pimping and few folks are offended. While the government decries adult travel, they certainly do not complain about the income it brings to Costa Rica Obviously there are also escorted tours that are not involved with prostitution. The content of the web site will be pretty much tell you right away if you are where you want to be.
