Tica is a what a native Costa Rican woman is called, it has nothing to do with being a puta. (A Nica is Nicaraguan.)
The center of the action is the Hotel Del Rey (HDR). I would recommend staying there, but there is a $10 "guest" fee for each girl you take up to your room. Check their website:

The girls there are independents so you negotiate the price with them. You don't have to speak Spanish, most know enough English to do business. The average price would be about $75/hr. Keep in mind, most will start negotiations at $100/hr or more. A TLN (all-nighter) will cost you $100-500, depending on how rich or dumb you are.
There also many massage parlors (aka brothels). They charge a fixed price for either a half or 1 hour. They range from $8-$47. This link will take you to a list of all of them:

Before somebody suggests the street walkers, don't pick up any street "girls", it's all TRANSVESTITES
