Make your own. Just your name and cabin number will suffice..............Wilba.
If you are sailing from Palma you will be issued with your cabin labels when you arrive at the dockside....the cases are offloaded from the coach (just realised you arrive by taxi so will probably take your own cases with you into the checkin hall!) to an area by the gangway...you go through the checkin procedure where you are given an envelope with luggage labels, doorkeys etc.......then make your way to the gangway where you identify your cases and put the labels on...then you go onboard and are shown to your cabin....Simples!!
Morris is spot on.
