Good: Larger rooms (especially the king rooms), resort is spread-out (you never feel cramped), beautiful rooms, beautiful landscaping, peaceful, sandy beaches, Banana Cabana, hammocks, lots of shady spots thanks to all the trees, and a great gift shop. Some of the most beautiful photos I've ever taken were right at this resort.
Bad: No elevators (this was tough for my mom). That's about it - I can't really think of anything else that could be considered bad.
