Going with a resort photographer is kind of dicey, since they might be hired there because they have connections, or give the resort a cheap rate. You'd be better off getting your own photographer if you have a specific style you want, and you might even get a cheaper rate since they get to go to a gorgeous tropical destination with you. We found this http://www.gatheringguide.com/ec/photographers.html helpful when picking our photographer, if it helps you find someone reasonable.
