If you are planning a trip to Vegas, please purchase your tickets to the Mob Museum before stepping foot on the plane. It was so worth the time spent there. We were told by someone that we would need at least 3 hours to get through the entire museum. We laughed at the idea, since we had to be somewhere else in 2.5 hours. Well, we ended up having to speed through the last floor at the end which was unfortunate because everything was so interesting. Add me to the list of people who have always been fascinated by the mob. From movies to books, I just want to know it all. This place is for people like me (and you?). The museum focused on the organized crime as well as the law enforcement that tried to take them down. The whole museum is interactive and full of real pictures, recordings, articles, hand written letters, etc. There really is just so much to take in, so make sure you invite someone who is also interested and won't rush you through the floors. There's three floors with tons of information about the history of the mob on each one. Don't leave Vegas without checking out this museum.
