The Mob Museum is a super cool place to spend 2-3 hours when you need a break from the hustle and bustle that is Vegas. Tickets are cheaper online, and teachers (even those from outside Nevada!) get a good discount.
Spread out between three floors, they did a great job of making it interactive, exciting and educational. There are even parts where they make a group stop and watch a movie to help alleviate crowding. On the second floor they also have a HYSTERICAL photo shoot, and pictures are only $8 with free online access, so we caved and got them.
We enjoyed our time here and learning a little more about Vegas history, too!
