Golly!
All I can say is that price shopping isn't always all it's cracked up to be, usually one agent pricing a specific trip comes in with a price very similar to another. There are times when one price might blow another out of the water, or that can't be matched by another agent - that's life. The best thing you can do is find an agent that you feel comfy working with, who is responsive and has your best interest in mind. Working on a trip for 17 couples is no easy task, trust me, it's quite time consuming so that's something you'll want to keep in mind as you begin your quest.
