Seeing a place from a different vantage point always makes it stand out. Getting over the keys was one of the best ways to enjoy the view. We even got to see some marine life (sharks and rays, etc.). The different colors in the water helped appreciate & perceive how shallow some places indeed were.
In addition, getting to view the ship wreck made the experience complete :)
