we are coming down at the end of the month (20-27) and I was wondering if the cruise ships are in on certain days of the week or how to find out. We are taking the kids to shark ray alley and don't want to run in to the crowds from the ships at the "touristy snorkel" sites.
If you charter you own boat or if your group is and guide is willing, then going to sites on "off peak" hours is awesome.
I went to Hol Chan the other day. At lunch time - I was the one and only person there. Snorkelled around and enjoyed the wild life at my leisure. There were schools of fish that were acting as if I was just a part of the group.
I left right when a small boat with 4 people on it arrived. They told me that they even spotted a large turtle.
