Yes, during the full moon of March, April and May they run trips to the Gladden Spit where the whale sharks come to feed. They had lots of photos, very cool!!
I ended up not diving, just snorkeling 6 times because the snorkeling was incredible! The southern barrier reef is virtually pristine, the water clarity amazing and we went to a different spot each time. Saw tons of beautiful corals, sponges, reef fish, squid, stingrays and spotted eagle rays. I think you and Alice would love Hamanasi.
