FWIW, I've never gone to anyplace twice except the Channel Islands and freedive spearfishing trips to Baja. Always seemed like there were too many new places to try. You said that you're going "back to Grand Cayman in April". I did that trip in the 1980s, including the Southern Cross Club on Little Cayman, and although that locale had the prettiest reefs I've ever seen, I'll never go back - too much else in the world to see. I advocate creating a flexible lifetime dive plan - I refuse to use the term "bucket list" - that takes me everywhere of interest once. Just lately I've been really intrigued by the possibility of diving the areas of the Pacific that were used for nuclear testing right after WWII - no more kids for me anyway, so.... And maybe Truk next year. Life is WAY too short to get stuck in a dive rut. Unless, of course, the White Seabass are running....
