You will have a great time! As far as good reggae shows--keep your eyes out for the signs along the road and on the beach advertising, they change the signage and keep it current. Roots, Alfred's, Boat Bar, Bourbon Beach and sometimes some other places have shows different days and times during the week. The Jungle is more of a dancehall, club vibe--and wasn't really my kind of thing as I prefer more roots reggae. That said, I did go on one of my trips and had fun checking out the scene. Explore the beach--stop at different spots, and don't sweat the vendors. Sure they can be aggressive at times, but for no thank you was all that was needed--or even just a shake of the head indicating no. They never bothered me--but maybe they can tell I am not made of money. And I have had some great conversations with some of them that had nothing to do with them trying to get me to buy anything--just talk and chit chat about life in Jamaica.

I wish I were in your shoes and going there in a few days time, how exciting!
