I was personally a bit disappointed in the Poly CL. The location is great, as others have said, its easy to grab a few things and head to the pool. The food was a little underwhelming to say the least. Oatmeal, cereal, and very basic continental for breakfast, you know the usual cardboard bagels and one toaster. The fruit plates were nice, but seldom replenished. Coffee was awful, but that's to be expected I guess. Also while the amount of tables is nice, the actual area is very cramped. Evening service was nice, although only two hot appetizers of Costco quality, but nice fruit and cheese plates. Desserts are the usual too, good cookies, while fancy stuff looked better than it tasted. A few staff members were excellent and friendly, but most were kind of phoning it in, not greeting anyone or talking amongst themselves ignoring the guests.
It's not on your list, and it's been a few years, but I really loved the AKL CL. It was a farther walk to the room, but the offerings were much more tasty and special. That was back in 2010 though, so I can't say what budget cuts they've went through.
