@Mike - really enjoyed the spot-on review. FWIW, the adults pool is heated, though it could easily be 5 - 10 degrees warmer (but it was nowhere near as cold as the large pool). An interesting feature in the adults pool (although not very practical in the winter) is that there's a cold spa in one alcove of the pool area. Probably a great feature in the summer, but not in January.
A couple additional thoughts...
The adult show in the evening was bad -- like laughably bad. I'd say probably on par with a middle school production show. We only went to one and decided that was more than enough. 😉
The lounge was awesome. I know you didn't review it (and probably didn't see much need for it, given the nature of an all-inclusive resort), but they had a great spread of food throughout the day, which was particularly useful when we slept late one morning. We also appreciated the spectacular views from the lounge terrace, which we didn't otherwise have from our room, as we had a swim-up suite at the adults pool. For those who may be debating on a swim-up room vs. a view room, I think going with a swim-up room while making use of the lounge is a great way to experience both. (Keep in mind the adults pool swim-up area is heated, and can be requested - though not confirmed - by reaching out to the concierge after booking.)
