My 10 year old daughter & I got the combo ticket to visit Sea Life as well as Legoland which is right next door. Paid extra for the photo pass, but there was only 1 photo op in Sea Life and 1 in Lego Land (on one of the rides) which didn't upload, so overall not really worth paying extra for.
Aquarium was wonderful, although seemed quite a bit smaller than the one in Minneapolis, particularly the tunnels. But still a lot to see and enjoy - loved the sea turtles and hearing one of the workers talking about how the one turtle only has 3 flippers and another one's shell is all bent up so he has buoyancy issues. They were beautiful, but also a reminder that we need to take better care of our oceans.
I don't know how long we spent in here; maybe less than 2 hours, so definitely make time to visit - it's worth it!
