Mob museum is very well thought out. You work your way down from the 3rd floor and it's very interactive. My girlfriend and I had a good time here. Very educational and cool at the same time. You may want to split the tour in half because it's said to take approx 3hrs and from what I remember you can go out n come back as long as you have your wristband on. Check on that prior! It shares history in a historical building! A must when your in Vegas to learn about old Vegas.
