I am going with the Royal package at the RIU - Montego Bay. I am adding addiitonal photography and flowers, decorations, disco rental, band, etc to the tune of approx 7G. This is separate from my attire, airfare, OOT bags, etc, costs for guest not staying at the hotel, extra decorations, costs for guests we are paying for, wedding insurance, etc.
I would narrow down where you want to get married at and do a cost comparison based on your MUST HAVES and the associated costs. There are tons of posts and threads on every subject imaginable so good luck to you--don't stress.
