I havnt been to the sandals in st Lucia, but I have been to st Lucia.. I went to jade mountain, you'll have to google it, it was extreme! I loved the place, the whole island was awesome and I recommend it to anyone who wants to get away.. I went for 7 days and shut the phone off when I left Miami and turned it back on in Miami when we got back and never missed it while I was down there! Jade is super exclusive, super expensive but super awesome! Sandals would probably be cheaper and still pretty dang nice! We have actually talked about going to the sandals down there sometime.. The water is super clear and when we went in may it was about 85 degrees average with I think 80 degree water temp? It was great!
