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!:)

Costa Maya can only be booked through cruise ship hence, very pricey. You have two choices in Cozumel Dolphinaris and Dolphin Discovery. I have been to both and personally find Dolphin Discovery nicer. Dolphinaris's food and drinks where sub par, the facility itself was nice and clean but nothing to do after swim, no pool or access to ocean. Dolphin Discover has a pool, access to ocean and a sea lion show and if you call as opposed to making reservation on line they add a free swim with manatee experience with dolphin swim. Both require a cab ride, Dolphin Discover cab and cost slightly higher than Dolphinaris but well worth the extra money. I just booked over phone for a cruise in May and was given 50% off, just FYI
