kurz, we are getting married at the GBPJ in about 2 months And I can let you know after the wedding how it was.. When deciding the resort, think about the location you want to be married in, beach, gazebo, etc.. And the number of people attending will also help with the decision..
What I would do is contact the wedding planners at both resorts and have them send you the wedding planning stuff.. it will have quotes with prices and details of what wedding they do and where
Hope that helps!
