My wife & I leave on Saturday (9/15) for the Bahamas on our first cruise. I have two unrelated questions ... 1-passports, when you leave the ship for excursions do you take it with you for ID purposes or leave it in the room safe? 2-looking for one of the beginner scuba excursions and haven't ran across one being offered. I wanted to know if anyone had been on one while in the Bahamas and could recommend one? Thanks everyone!
