Well I don't have 100 guest coming but close to it! Ceremony will be at the resort, but very simple. We chose to do a Catamran Cocktail party instead of a dinner. The cost of the catamaran, transportation to the dock and upgraded menu worked out to about $48/person. so not bad at all, plus it's something different. We used Island Routes and they were fabulous to work with! Hopefully it all works out when we are down there!
