Comfort Suites knows the cruise ship people are just renting rooms for Atlantis passes.... and they dont' care. Most people, like myself, just check in and check out at the same time, then you dont' have to go back over to ComfortSuites after you are done. So they are making money doing nothing for you but a 5 min check in. The kids meals are HUGE... like 8 chicken nuggets. I had myself and my two daughters age 10 and 7, we got one adult regular chicken sandwhich, a chicken nugget kid meal and an order of nachos and I was looking for people to give food to, we had a ton, so you can definitely share your meals.
I am not sure if they let you look around the pool area without getting a wristband for either aquaventure or the beach day. They had someone by the one door checking and they stopped us and asked for our card from CS.
We absolutely loved our day at Atlantis.
