I have been here both before and after the remodel. I must say I love what they have done with the place. The new hippo exhibit and shark tank is the best by far. We go in there first to avoid the crowds and usually end up there in the end as well.
I think parts of it are a bit narrow, especially with the many strollers being pushed through. Also, some of the tanks are a bit high for little legs. Kids love to touch the fish in the tanks.
It is a great raining day trip or go and bring a lunch and eat by the river. Go early or late to beat the camps and class trips.
