interact with dolphins

We (kids will be 6 and 8)will be visiting Costa Maya and Cozumel. I want to take them to interact with the dolphins but not sure which place/port would be the best. Anyone that has done both please give me your advice.

thanks!:) I also posted this on the Costa Maya board.

Check out Chankanaab on Cozumel - not sure they will be old enough to swim with the dolphins.

Thank you. Figure they will only do the dolphin encounter.

Good thing about Chank is that after the encounter you can stay and enjoy their small beach, snorkel area, sea lion show, etc.
