I have booked this shore excursion with the catamaran ride and snorkel at shipwreck cove as I do not think I want to be on an excursion the whole day. The two adults going are very athletic but no snorkeling experience, so not much to compare to. it was a good price at $50 and it only goes till 10:45 which will give us time to go back and have lunch on the ship (I hope) and then possibly go off and shop a little bit. I like not having an excursion the whole day and 7:15 was the only offered time. Is the port close to stuff to do on our own after the excursion? Has anyone done this excursion before? Is it worth it? Is the snorkeling good for a first time? Any feedback would be great.
