They actually don't recommend carrying your passport when you leave the ship. You get cleared through/immigration customs on the ship and then just need to carry a photo id and KTTW card. Of course, if one chose to use the passport as a photo ID one could do that.
Last year when we went through customs in the Bahamas (went to Paradise Island) they said passports were going to be required. Is this true or is a certified birth certificate still sufficient?
