This will be our 4th cruise but 1st Western Caribbean. I would love some advise on these new ports. Our ports of call are Cozumel, Grand Cayman and Falmouth. I am looking for advise on the best dolphin excursion in these ports. Also other excursion recommendations for a family of 6 including grandparents, parents and DD 19 and 10. Which ports would you recommend booking excursions and which ports are fine to just explore on our own.
