For $25 this was kind of a rip off. The walkthrough took all of 25-30 minutes, it's pretty small. This is like a free to $10 attraction, even on the Strip. There were some really cool exhibits and it was very clean and pretty.
Also, it's way down on the end of the Strip so you can't just conveniently pass by it unless you happen to be down there. You do get to touch sting rays, which was cool. But I guess all in all I just felt like there wasn't near enough there (5-6 rooms if I recall) to justify a ticket price on the level of the Mob Museum (3 freakin stories), the Wax Museum (huge, plus a 4D movie), etc.
