Been wanting to make a trek here but haven't had a chance til now. This is definitely a MUST do in Vegas, especially if you are like me and grew up coming to Vegas as a child and remember the old Vegas. This was a trip down memory lane for me!
The tour guides were great and did a wonderful job of mingling in lots of old Vegas history. You can also take all the pics you want which is nice but be warned the tour moves kinda fast and they don't allow you to lag behind.
Also, be sure to reserve ahead of time cuz our Thursday morning tour was sold out and walkins were turned away. I'd also suggest bringing a jacket cuz a lot of the signs are in the shade but even on a somewhat warm day it can be chillly. The Boneyard Park across t he street is interesting too.
My only constructive crisitcism is that they need to add some addt'l seating in the lobby -- tour size way exceeds the # of seats available so get there early if you wanna sit while you wait.
