So I'm going to Cozumel in the summer. I'm pretty excited since I've never had much opportunity to travel, and I want to do lots of stuff. I came across a few companies offering whale shark swimming tours that I'd REALLY love to do. But I want to make sure it's like, not disruptive to the sharks or anything. Any things I should look for to make sure of that?
Look for accreditation, especially eco-accreditation etc. Check out the schemes to see who else is accredited, that will give you a good indication if there validity.
