We went to the aquarium while on a family vacation with our 7 month old daughter (my brother was there with his 16 month old daughter as well). Both girls were able to enjoy it and there was no cost for either of them. Overall, I'd say its a bit pricey ($25 per adult) but as a one-off it was worth seeing. We really enjoyed the sharks lagoon and the music playing in the background was so relaxing. Our daughter loved the penguins especially the tunnel out into the middle of their enclosure. She got a big kick out of the pods in the kids area the let you go up into the middle of the fish tanks.
