Experts, I've snorkeled while on all the islands. In all cases I've found just as good snorkeling right from the shore, if you know the spots, as when taking a snorkeling tour. Case in point, in Kauai I've found far better snorkeling off Tunnel's and Hideaways than when I took a Napali tour. So, with precious time on Maui, what are your thoughts regarding Molokini? Does it really deliver a snorkeling experience that I have not had in the islands in general, in terms of quantity and variety of species etc. etc.? Thank you!
