Just returned 3 weeks ago and we had our 2 1/2 year old grandaughter with us.
Her highlights:
Bring something to get wet in and a towel. If its warm enough they love running through fountains and we saw them everywhere. She spent more happy time doing that. We did the dolphin show and she loved that but her attention span didnt allow us to stay the whole time. One thing to note. They dont allow strollers to go in anywhere it seemed. But when we went to the dolphin show my grandson (5 months old) fell asleep and they allowed us to go around and bring our stroller in the top entrance. It was easy to slip out unnoiticed too.
She also loved the Penguin Encounter a lot.
The shamu show was good but again her shorter attention span made it harder. Lucky she got so tired so she was in a trance on my lap.
We missed the Happy Harbour because of the storm that rolled in we decided to call it a day.
