You really don't need to book an excursion for Grand Turks unless you like to scuba. The port is right out side of Margarittaville. There are complementary chairs on the beach and there is a great pool, restaurant and swim up bar there as well. You can rent snorkel gear for $5 and do all kinds of water sports. My 2 boys (13 and 15) did the Flo Rider there and had a blast. The crew who ran the ride were very friendly and helpful. This was probably the best stop on the cruise..you got the best of everything in one stop. Not to mention it was absolutely gorgeous!!
Waste of time getting off the ship...only good thing was Fat Tuesday and Senior Frogs.
Did our own tour and walked around Old Town and the fort.
This excursion was a blast. The crew on the Castaway Girl was awesome. We took a catamaran out to snorkel and swim with the turtles. Highly suggest this trip. Don't be turned off by 75-80 people getting on the catamaran there will be room on the bow once you do the safety briefing. It was a wonderful experience!!!
