Extraordinary! Everyone in the family had that reaction that if this were the only thing to have done this entire vacation, this 1 hour was worth everything. From the crew’s engaging ways to their quality of gear and clarity of instructions and then support during water activities, everything was totally above the bar. And the Manta Rays, oh… what can I say? There were so many!! I counted 11 at one time, all together… how they float up from the depths, do somersaults, some even were daring to swim all the way up to within a feet of our faces. Such gentle creatures, so magnificent! If moments like these can’t infuse in us to save our dear planet, nothing else can! Some swimming experience will be required but you don’t need to be a strong swimmer at all. Highly recommended.
