One of our excursions during our Christmas Carnival Cruise 2017 was to the Central American country of Belize. We narrowed down our excursion choices to cave tubing, scuba diving or hiking the Mayan ruins. Last year, we snorkeled in caves in Riviera Maya so cave tubing was voted off the list. While scuba diving at the Great Blue Hole sounded remarkable, being novices, we’ve really been planning on a full scuba instructional vacation, and furthermore, the phrase “heavily inhabited with sharks” left the Mayan ruins as a fine selection. Besides, we already had water based excursions planned for Honduras and Mexico.
