We stayed at the swan in aug and our 3 ds 15,13 and 11 loved the grotto pool. I would say it is on par with storm along bay. Yes by the waterfall it is a little cooler. There is also a part that has water volleyball which our kids loved and they did , however, say the slide was lame and slow compared to the volcano slide at the polynesian. Also, some parts of the pool are pretty deep, like at least 5 feet, so if your kids are not good swimmers you might want to bring water wings etc. I dont know what they have there that you could borrow etc. Also I did feel the one lifeguard on duty was a bit inattentive. We saw the storm coming and he should have got everyone out long before we made a quick dash during the thunderclap. Also I feel he had alot of area to cover and was sitting in a rather awkward position to have a full view. I am glad my guys are strong swimmers. Also the lounge chairs are great. You have your pick and its not crowded, at least not when we were there. I did see a few people smoking which annoyed me, since my ds has bad asthma. Also I saw there was a sign, no food or drink on the deck (this was the grotto pool.). I really did see it only after we were having our gatorade and snacks. No one said anything to us.
