I've been planning to take the divers certificate ever since I was old enough (my relatives are experienced divers, so I learned to "free-dive" at a young age) but I never got around to it. Maybe I have it next time I go. But they have tours to the ruins with glass-bottomed boats, and I'm planning on going on a snorkeling tour there I saw being offered (of course, this is if the weather permits...) It's apparently shallow enough there :) But yeah, definitely next time I go I'll have my divers permit! ^-^
