Where in the World?

I have taken a few days of R and R. Where am I?

  • I have gone swimming all the way through a cave made famous in a film;
  • I have gone swimming with nerf sharks;
  • I went into a bay and fed some swimming pigs;
  • I went to an island and fed some iguanas;
  • I was swimming and a barracuda swam after me;
  • I lounged on a sandbar where a famous Web 2.0 exec got married;
  • I went jet skiing around a plane that crashed in the water.
