I suggest checking with your local travel agent or AAA. They can be very helpful. I will say this...make sure you have everything you need in your carry-on, since it takes some time for your luggage to be delivered to your cabin...sometimes not till the middle of the night.
Also, make your luggage identifiable like tie a bow or scarf on each handle. When you go to claim your luggage at debarkation...well, you'll see. a mass of luggage, mostly black, and you have to wend your way through the rows...the bow will make your luggage stand out! Enjoy your cruise, I've been on 3 and can't wait to go again!
