We really enjoyed all the shows especially the rescued animals show which featured all kinds of 4 legged animals - it is amazing how they have trained cats, dogs, pigs, etc to do such amazing tricks - it was very enjoyable. I just found our SeaWorld map and this show is called Pet's Ahoy and it is in the Seaport Theatre.
There was also a show called Blue Horizons and it was amazing - it was a combination of acrobatics, birds and dolphins. We found all the shows to be top-notch and entertaining - my son was only 3 at the time but he enjoyed all of the shows.
We did some of the rides in the Children's area but the shows were the highlight. Enjoy your visit.
