Sorry for the jab but all kidding aside, you will have a great time and you are on the right track. If RS is on site found out where there boat departs, number of divers and dive times. Kimpton is so far up that if the boat leaves the property it is not likely to be full of cruisers. A couple emails to a couple ops should get you all the current info you need. I also always check Cruisett for any island I am on diving to see the schedule of ships and plan accordingly. Other than its disproportionately large size, Kimpton is on a great stretch of beach and I have to image it will be wonderful. Enjoy your trip
