Overall it was a good experience, just too long. Definitely got to see and swim with several whale sharks! The boat crew was great and made an excellent lunch for us. I'm not sure why the tour guide was surprised that most didn't want to stand in the chest deep water at Isla Mujeres after our time with the whales sharks. We spent too much time there. Why have us stand in the water for more than 30 minutes? Roman went to a beach vendor and had time for a couple of smokes on the boat while we stood in the water waiting for lunch, which was tasty. Some of us would have preferred a shorter stop so we could get back to our hotels for beach and beverages.
It took us a very long time to get back to our hotel. Rush hour traffic was horrible and it seemed we had to stop at every light, at which at least 4 cars would go around us when it turned green. Roman got out before we did which I thought was odd.
Overall it was a great whale shark experience but be sure you're ready to be out of your hotel from 6 AM to at least 4 PM, we got back about 4:15.

This tour was better than we had hoped for! Went with my daughter and her boyfriend and our french tour guide from EcoTours could not have been more helpful, enthusiastic, informative or kind. Clare did everything possible to ensure everyone not only enjoyed the experience, but had a GoPro camera to ensure we all had photographic and video memories available for a very reasonable fee to remember and share with family and friends. We went on this trip on July 29, 2016. Yes, it is a long day - we traveled from our hotel in Akumal to north of Cancun by minibus, then well over an hour by small boat to find the whale sharks. And yes, we were extremely fortunate to see and swim with many whale sharks and even manta rays. And yes, I would advise taking sea sickness tablets the night before, and the morning of the trip if you suffer. The ocean was quite rough the day we went, and the time waiting on the surface in between dives even began to get to me after taking these precautions! However, no one on our boat was sick, and we were fortunate to have the most exhilarating experience swimming with the whale sharks, with people who respect the ocean wildlife, with an amazing boat captain and mate, who managed to steer their way safely between many, many whale sharks, and quite a few snorkelers and who were determined to help us make the most of this opportunity. The only things I would change are a I would have booked this tour earlier in our trip, because my husband became ill from food/water and was unable to join us, and b I would have rented the wetsuit offered instead of wearing a life jacket, which was restrictive and a bit annoying for a reasonably strong swimmer and PADI-certified diver. But this was a fantastic experience - quite awe-inspiring and humbling to see these beautiful creatures in their natural habitat.
