We did it through Princess in Cozumel pre-hurricane. It was totally awesome. They are such magnificent creatures, and so intelligent. One of the ladies in our group had shoes on, the dolphin wouldn't have anything to do with her. As soon as she took them off, voila. As powerful as they are, to drag me around, they are extremely gentle. They didn't butt into you, the came up right beside you. They even swam in between the group, without hitting any of us. To me, it was worth every single dollar to be able to interact with them. They did pull us, they kissed us, they let us pet them, they splashed us, etc. I wish it could have been longer. Have a wonderful time!
They didn't pull by the dorsal, they swim underneath you and pull by whatever you call the side fins. They didn't do a foot push with us, it doesn't mean that other places don't. They did a kiss, and let us pet them, they splashed us, and swam with us, they waved and talked to us. Like I said, it didn't last long enough, but it was awesome.
