They have a Komodo Dragon!!! Need I say more?
Oh, and you can PET the STINGRAYS! So cool.
The tunnels are the best part, IMO. Especially when a shark decides to swim right up against the glass. Amazing!
We've been there twice (we're locals). If you are looking for something to do that's still on the strip but not so "Sin City," check it out. You'll get to see some cool stuff and learn something, too!
It's not huge. Remember, this is a casino attraction, but it's still impressive for Vegas. If you can get a locals discount, do it. It's worth it.
