OK, hope it works out for you. Another option might be to contact TTOL sponsor Wilfred Brooks and ask him how much he would charge to take you around for the day. Wouldn't have to worry about parking on Front Street or in Marigot, and wouldn't have to worry about drinking. Spending an extra 10 minutes parking or walking from a parking space far away isn't a big deal if you're on island, but it would make me cranky on a ship, knowing I only have so much time. Regardless, enjoy your day with friends, showing off the island!
