They never said. After we buzzed off the ship and before we hit the gangway there was a security guard that took them from all those that boarded in Rome. I think it was to prevent you from reboarding the ship. The red sticker was also used to show to crew in Barcelona while muster drill was happening from those that embarked there.
Had we known they were going to keep them we would have gone to guest services and asked for replacement cards.Would have lost ours somehow. 😉
If they wanted it, like us, they would have let you know. By chance do you still have it, and if so could you post a photo of it? I’ve never seen an orange one before. I guess people are still asking about your orange cars today. 😀
