My nieces all had lanyards for their cruise cards. One day while in Jamaica, my niece realized that her card was gone. She had been continually click her card clip on and off all week. After an unsuccessful search for her card, my sister had to go back to the ship and go to guest relations to have a new card made. Then she had to go back off and through all the security check points to where her daughter was waiting. Luckily, her father was with her. If not, my niece would have had to wait alone as she was not allowed to pass security without the card.
