My advice to the OP would be to look through the provider ads for this area. Ask those who visit often why the visit often. If the answer is "the beach" more often than not, that may be the end of your research. If those who visit often are making good money, compare your rates to those who visit here frequently, and compare yourself (age, menu, online persona, etc.), realistically, to the providers who visit often. If you compare favorably, you should have a good trip. Another question you can ask providers who visit often is: how many of the guys who express interest actually book?
In sum, why do others visit often, how do you compare to them, and how many appointments can you expect? The answers should help with your decision.
