We are 3 families looking to change our post-Xmas family get togethers for a one week getaway to the Caribbean from dec 28, 2013 to Jan 4, 2014. We want an all inclusive resort with a minimum 4 to 5 star rating. It MUST be warm at night so Cancun I think is out of the question. We have Jamaica and/or Punta Cana in mind. Any suggestions? We are leaving from Montreal. How soon should we book? Thanks for your help.
