I've seen the traveling Real Bodies exhibit several years back before moving to Vegas and really enjoyed it. I meant to make my way here since moving but never found the time until a recent promotion for free admission for teacher appreciation week- as a former science teacher, I totally had to take advantage.
Located in the lower level of Bally's near the food court, they've made good use of the space and organize the exhibit by body systems (skeletal, respiratory, organs, reproductive, etc). The bodies on display were cool and the info provided on plaques was detailed without being overwhelming- this wasn't as text-heavy as other museums. The section on blood vessels was more interesting than expected, and I was surprised to see they included a section on fetal development.
Regular ticket prices are $25/adult and I spent less than an hour here- not the best value but a good "educational" option to have on the Strip, and there are various discounts to be had on Groupon, etc. Note that if you spend more than an hour here, you will also pay for parking.
