When I was on the Disney Wonder in the Mexican Riviera I was lucky to catch the biggest pod of dolphins in my life (at least 300 or 400) and I spend a lot of time at sea being an avid scuba diver. I have also been fortunate enough to see many whales during many of my dive trips but the most diverse including a pod of killer whales was when I was on an Alaskan cruise (non-Disney). I have never seen dolphins or whales when sailing in the Atlantic Ocean but I am sure they are there.
