I agree with the other posts, 2 might be a bit much like a work schedule. Also, the difference between the written word descriptions on these tours and the actual tour could be quite different. If you do plan 2 shore exc. on any given day, perhaps consider booking the afternoon excursion through the ship, even if it costs a little more $. We were on a tour where the bus broke down, and were late getting back to the ship. However, since it was booked through our cruise line (Celebrity) our ship did not leave port without us. Enjoy your trip!
