First time cruiser and passport holder here! Do you take your passport when you go on shore excursions in Bahamas, St Maarten and St Thomas? If you do, how do you keep them safe from other people and dry while you're in the water? And If you don't take them with you, suppose you miss the boat without your passport on you? And the very big question, will I get my first passport stamp at one of these locations? :-D
