Hello jocobo,
I just started myself and we are having the wedding at Moondance Cliff in Negril. there is tons of info on this site, if you find Jamaica and then accom and site, there is tons of threads on individual location. We just came back from Jamaica looking at various places from Montego to Negril. I think some of it is budget and some of it is style. Do you want big resort or small resort? Once we nailed down which resort we wanted to go with, rest came easy. well, we are not even close to done but it is just getting easier... sigh
