Hi @brye858. Congratulations! I am getting married 6/11/15 at Iberostar Rose Hall Suites and did extensive research before deciding - it is the hardest decision! Are you looking for adults only, or family-friendly?
We REALLY wanted to be in Negril because of the gorgeous beaches and sunsets, but the options for family-friendly all inclusives were few and we wanted to allow for our guests to bring their children. We looked at the RIU Palace Tropical Bay in Negril, but it seemed like there were A LOT of extra costs for the wedding. The big deal breaker was that they do not have an on-site disco and with wedding receptions ending by 10:30 that just wasn't going to do for our group! No way we were going to corral people to go off-resort at that point and also no way we were going to be ready for bed. I was also not wild about the locations to have the actual wedding ceremony, and they do up to 4 weddings per day.
The benefit of IRHS (Montego Bay) for our guests is that it is close to the airport. It is also centrally located to both Negril and Ocho Rios for day trips, in addition to Dunn's River Falls and the Martha Brae river. Also, Iberostar does only one wedding per day - I don't have to compete with another wedding for a ceremony time or reception location. The reviews of Iberostar are all so positive and the resort itself is beautiful, that it put my mind at ease the most
I hope that helps a little bit! If you're okay with adults only you'll have many more options in Jamaica!
