We went on Sunday morning and there wasn't any crowds. Would not recommend to go if there is a crowd. There were only a couple of interactive actors. They were really good and didn't break character. Overall ROI I didn't think was worth a full price $33 (we got a local discount). The exhibit was good, but you learn more bout what they wore, life at home etc. not much of what they did in the mob. If you are bored in Vegas and can get discounted tickets check it out.
