Here you go.
The wife and I took a Powerboat tour from Grand Bahama down to the Exuma Islands. Cost me either $400 or $800 for the two of us - but whatever we paid - I would have gladly paid triple and been happy I spent the money. About a 45 minute scarab ride across the ocean, swimming/snorkeling in a lagoon, feeding sharks, feeding iguanas, catered lunch/drinks and snorkeling..
Best money I've spent. They launched about 2 blocks from The Atlantis where we were staying. It was absolutely incredible. The only time in my life where I can say I've felt like I was in "paradise" and we are VERY well traveled to tropical locations.
