I went to Negril a couple of years ago, and by the time we got to our hotel, it was pretty dark. So I suggest to get an early flight. I went w/ 2 of my girlfriends and, I don't know about Ocho Rios, but that ride was border line scary. I guess they really don't enforce driving laws...Thank goodness our driver was playing really good reggae to take the edge off.
We had such a blast in Jamaica, maybe a little too much fun, The vibe, the people, and the MUSIC is so awsome. Congratulations on your engagement!
