The New York Times (online) Travel section has a really good article ‘Affordable Caribbean: Puerto Rico‘ focusing on the north west region of Puerto Rico and the town of Aguadilla. The article is written by John Haskins and details affordable places to stay, places to eat and party, as well as what to see and buy.
The west coast of Puerto Rico is served by the Rafael Hernandez Airport in Aguadilla, that has direct flights to the USA through JetBlue, Continental and Spirit.
