PART 2 -- I had about 6 min and my wife 3. Admittedly we had 3 boys to assist, but allotted time was unacceptable. On the (slow) ride back, someone said that the boat seems kind of slow, last time we made better time...the driver responded, "if I get back too quickly, we have to wait for buses". To which I commented -- "then how about we spend MORE time snorkeling?" . He said nothing. Oh well. Caveat Emptor.
