You want to be careful though. Do not use them if you are arriving the day before. They may be taken and held aside until the next morning and you won't have access to them. If you are arriving the morning of, use them and then you will have no need to worry as they will take them directly to the ship from the airport for you, even if using your own transportation.
If you decide to come early and keep them, you will have to have them on by the time you arrive to port and leave them at the tent so they can make it to your room. They will have you fill some out if you don't have them on.
