Congratulations on your engagement!
We will be getting married at Couples Ocho Rios on April 19, 2008. It really depends on how many guests you'll have. Whether you will have any kids in the party or not. If there will be kids, consider Riu or Beaches. If there will be no kids, try to look into Sandals or Couples. We chose Couples because it is more afforable than Sandals, we can customize our package more, and all the excursions are included as well.
Good luck and happy planning!
