I went 2 years ago with my family. It opens at 10 am and is slightly pricey at $18 for adults (should have looked for a coupon). Its damp throughout the tour and my damned sinuses clogged just walking in the door. The exhibit itself was very good and the youngest ones were thoroughly impressed. I would recommend it especially if you can get BOGO coupons.
Thanks, Weggie. We'll be at MB next trip and may use a MyVegas reward, so it would be free. I don't mind damp, I live in Florida. Anyway, how much time do you think we should allow to see it?
I haven't been yet but I'm going in this month. It says they stop selling tickets one hour before they close. So, I'm allowing one hour, give or take a few.
Definitely not a lot of time. MAX 2 hours if you stop and read every little detail. We used MyVegas rewards for it last year and liked the tour but definitely not worth full price.
