We are going on an NCL Breakaway Cruise next month. We received our luggage tags in the mail yesterday - 2 per person. We were planning on each bringing a suitcase as well as a carry on. If our carry on is a back pack or a closeable tote bag can we place one of our tags on it so we don't have to walk around on the ship that first day with our carry on until the room is ready? I did see where folks checked carry ons once they boarded the ship, but if we could avoid that altogether, it would be nice. Thanks
