I posted this on another web forum, in response to a question about air conditioning at the resort. Thought I'd add my $.02 here:
Spent July 22-29 at Sunset Waters and can't compliment them enough. No problems with air conditioning at all. Boats ran on-schedule and with great efficiency. Took advantage of the all-inclusive package, including six 2-tank dives off their boats and shore diving on their house reef that included my first-ever seahorse sightings (multiple times, resident on the house reef) and viewings of octopus, turtles, rays, eels, stonefish and some of the healthiest coral I've seen. Dive op (run by Lynn Bean) is absolutely top-notch, with a crew that embodies "customer service." I've heard Sunset Divers (the Sunset Waters dive shop) described as a "liveaboard-ashore" and it was wonderful. Others call it "valet diving" and I cannot disagree. My wife and I really liked being pampered and my wife was absolutely in love with just about every crewmember.
Food at the resort was good, sometimes terrific, with enough variety to keep things fresh. The beach-side buffet and barbecues were wonderful. Though we're non-drinkers, we did consume enough virgin pina coladas to more than make up for the AI extra cost. (Shoot, I ate enough desserts to justify the AI. Desserts were impeccable EVERY night. Uhhh, and lunch, too.

)
As for the diving, Mushroom Forest is an absolute must-dive. (See if you can do your surface interval at the "Blue Room." A neat cave spot.) Even better, plunk down the extra $50 for a trip to Watamula, at the northern-most point of the island for an experience that my wife called, "Mushroom Forest on steroids" and others called MushForest "times a hundred." I can only describe it as entering one of the grand cathedrals of the world, only underwater. Remarkably beautiful. Words fail me, quite honestly. As others noted, Makos Mountain, Porto Marie, Generation Reef -- even the house reef -- were all wonderful dives with an abundance of very healthy coral.
I must have said to the wife, "I love this place," a couple dozen times or so. No kidding.
