The best excursion in the Caribbean is in st Martin.. captain bob's speed boat excursion, it's a 5 min Walk from the Port, it goes All over the island and stop's at different beaches and a couple of stops to snorkel.. great fun, food and drinks provided, it's a family run company and has been in business for a long time. Captain Brett is Bob's son and now runs it and is alot of fun.. look it up, you will be back in plenty of time to board the ship.. Best excursion in the Caribbean..
