I have had multiple friends go to the Grande at St Lucia. They have all come back raving. None of them dove while they were on their honeymoon. My wife and I got married last year and we went to Cozymel for our honeymoon. We stayed at the Occidental Grande. The resot was beautiful and romantic. There are 4 restaurants. One is a buffett and the other three require reservations. It is an all inclusive and we upgraded to the royal club. They treated us like a king and queen. We made 17 dives with the dive op on site. We were planning on doing 10 and enjoyed it so much we did more. Some of the best dive sites are 5 minutes away by boat. The only negative was that we were a 20 minute cab ride away from town. This meant that we stayed on the resort most of the time. The positive about this was that we did not encounter any of the cruise ship traffic. There are 2 pools at the resort. One for laying out and enjoying the quiet and one for the more active. There is not much late night at the resort. We found that the resort and the destination suited our budget and desires better than Sandals on St. Lucia which was our second choice. Let me know if you want any more info. Congrats and good luck.
