Swimming with the dolphins was such a great experience that we sent the whole family (19) for a day which includes that and other close encounters with many varied and wonderful creatures. Just don’t know how to find a better experience for your youngsters and YOU. Just wait until you feel the powerful bodies they have....Wow!
Seconding the swim with the dolphins experience at Discovery Cove @ Sea World. My wife and I did it in May and they have added sea otters to the park since we have been there. I highly recommend it.
