We haven't thought about excursions. Last time we went we did excursions at every port. We did the catamaran races in Key West, String Ray City on the Grand Caymans (this is definitely a do again), a beach excursion in Cozomel where we did the banana boat ride and jet skiing, and then my son parasailed on CC. We had a blast doing them all. Now that we can book excursions 90 days out I need to start looking into those kinds of things.
