I thought this was excellent. Are there better ones around the country? Absolutely. But I still thought this was a well-presented attraction with loads of great critters at a decent price. I was also pleased to discover that it was larger than I figured it would be. (I don't know why I thought something in Vegas would skimp on size, but I guess I thought $16.95 seemed low for a Vegas attraction so the size must be the catch.) The free audio tour was very useful, and the touch-tank and underwater sections are fun. The staff is very knowledgeable. I suggest buying tickets online -- it'll save you at least the huge line at the ticket counter and the Will Call rarely has a wait. (Also, I was a bit confused, but I think you can get discounted tickets online also.) You may still face a daunting entrance line, but it generally moves steadily.
