I have only been to Turneffe Island Resort, and that was 6 years ago, so weigh my post accordingly. While it may seem from their website that they focus on fishing, that was not the case on my visit. All the guests (~15) were divers, nobody fished, and the resort was typical of well-run dive operations. The diving was excellent, too, because the resort is just a short boat ride from The Elbow, arguably the best dive site in Belize. The diving was off of skiffs, with up to 8 divers to a skiff, and they had a 42' Newton for the trip to Lighthouse Reef and the Blue Hole. The food was served family style, like on a liveaboard, and it was good. The private cabanas are comfortable and nice, in a traditional way (romantic, according to my wife)lots of wood. The setting is fabulous. When the wind dies down the insects can be a force to be reckoned with (you're sitting on the edge of a mangrove swamp), but they didn't bother us and I would imagine it's the same at the other spots you are considering.
