Use ONLY JUTA Tours in Jamaica. They're Reputable
Because Jamaica is one of the best tourist spots in the Caribbean (for various reasons which I will not get into), many people go to Jamaica each day.
If you plan to visit Jamaica, there are airlines flying there (USAIR, SPIRIT, AIR JAMAICA, AMERICAN, DELTA(?)). All of these have had good reviews.
However, while in Jamaica, many taxi "companies" and tour companies exist. Some of these are good but USE JUTA TOURS. They are reputable and has been around for years and years. There are no incidents with the drivers who are professional. They are members of Jamaica Hotel and Tourist Association (JHTA) , American Society of Travel Agents (ASTA) ,
Jamaica Chamber of Commerce (JCC) , and Caribbean Hotel Association (CHA) so they are THE COMPANY to use. Visit their website (http://www.jutatoursltd.com) before traveling because you can negotiate a deal with them.
