Hello. My family and I are going on our 1st cruise in May. We're debating on whether we're getting off in Nassau or staying on board. My mom went on her first cruise last July with my brother and his fiance, she said that when they got off in Nassau, to get back on board not only did they have to show their stateroom cards, they also had to have their IDs. People that didn't have ID and only had their stateroom keys were not allowed to go thru security. My questions is, has anyone ever had any issues getting back on the ship from any port using just their KTTW keys. My hubby and I have state issued IDs but our daughters do not. We won't get off of the ship if this is going to be a problem. We are not cruising with passports this time, just our birth certificates because when I initially planned this cruise passports were not and are still not in the budget with a family of 7. We will be vacationing again in 2014 to Jamaica and we will definitely have passports by then, just not this time. Thank you to everyone who responds.
