The comfort suites is very basic. But, clean, well kept and safe. There is a free continental breakfast which is good but plain. It did the job for us though. It is literally right next door to the Atlantis.
The Atlantis was amazing. Yes, it's big. So is Disney World. You go knowing this and plan for it. Try a different pool everyday (there are plenty). Ride the water slides. The lazy river is amazing and at a few places not so lazy. The aquarium, the dig, the web cafe, the restaurants, the art. It's all so amazing. You are treated just like an Atlantis guest. Just show your card and get a wrist band and no one knows where you started from.
We would leave our room in the morning and not go back until we needed to shower for dinner. We'd just reapply sunscreen in one of the spacious bathrooms. Then, we'd head right back to the Atlantis for dinner. Alot of the chairs have nice big awnings that go up and down so you can be in the shade or the sun, your choice.
My DH and I went for our anniversary and can't wait to bring our boys back in 2011.
