Hi Phil and Erin, Just curious if you've made your decision yet between Turks and St. Lucia? These are 2 completely different resorts and as already said above, one of the biggest differences is whether you will have guests with children or not. I've been to both of these resorts and they are both amazing. The overall beauty is St.Lucia is amazing and captured beautifully at La Toc. If you want amazing beach and some of the bluest water available in the Caribbean, the Beaches Turks and Caicos is the place for you. I have some beautiful photos of Beaches Turks and Caicos including several of the wedding gazebos with the sea in the back ground. Let me know if you would like to see it. If there will be no guests, then I would recommend the Grand St. Lucian as it is a more intimate resort.
