I have been to both and had the behind the scenes special prividges tour. Amazing aquariums and amazing maintance. Ripleys is #1 for a reason. It is worth the price of admission and is better than Chatty and even Atlanta. Atlanta is nice, but the design is not. I would rank them Ripleys, Atlanta, Chatt and the #2 and #3 are a toss up in my book. I must admit that the reef section at Ripleys is ............. hobby worth, but nice none the less. I mean that I have scene that size tanks in hobbists homes, and with that amount of reef life (corals, fish, crustaceans, etc) That is my 3 cents worth.
Randy, you gotta go back. I wish you all could go behind the scenes.
