A tip if you plan to ride the AquaDuck before you head to your staterooms (which won't be open for a few hours) - check in all your major luggage so it will be sent to your room and you wont need to wheel it around with you. Keep a small bag (backpack perhaps?) with everyones bathing suits and possibly sunscreen, etc. and whatever else 'essentials' you have with you (shades, wallet, medicine, etc.) - this way you can change into your suits and start having a good time at the pools without worrying about all your luggage, or forgetting your suits in your luggage! Plus you'll have your clothes to change back into (that you wore onto the ship) if you wanna wrap things up and have some lunch, or tour the spa, etc.
