You will get a paper from the comfort suites at check in. You then walk across the street, LITERALLY, into the Atlantis. Show the paper to the desk in the Atlantis hotel and they hand you the bands. Lines can be long to do this....so go as early as possible if you don’t like to wait! Just take a taxi from the ship to the hotel, lots of taxis are waiting for you, super easy to do. Hours at Atlantis vary according to the time of year, so check the Atlantis website. I will tell you they close early year round, like 6pm, so getting there early is best, lucky you! You will get more done the first hour that they are open than the rest of the day. (I stayed there for a week, so I can answer any specific questions! ).
