Very cool. Take the time to read about the mobsters. Some parts boring but interactivity is good. Someone needs to check that all things work properly. There are some duplicate boards.
The movie is good but doesn't really belong with the theme. Hollywood had no impact on Vegas so doesn't really belong. Consider replacing with Frank Sinatra and his role, as well as other big name stars.
Only you the visitor can determine how fun you want to make it when interacting with mobsters and police. Don't be afraid to go outside the norm. Maybe you want to be a model citizen? Maybe you want to be a mobster? Only you can determine your fate at the end.
Overall this was a fun experience and worth going to. Really appreciate the military discount.
