We live in Atlanta.  We purchased season passes to the aquarium it's second year.  It's just a wonderful place.  We love it.  Our 3 year old loves it.  And we have taken many out of town guests who loved it.  Everyone loves the Beluga whales the best.  The aquarium is clean and has amazing exhibits.  Probably the BEST place thing to do in Atlanta.  The cafe in the aquarium is great and very reasonably priced.  They have lots of variety too which is nice when you have young children.

No complaints about the aquarium!
