I have been waiting to see the Bodies exhibit for a few years now and I heard Vegas is one the best. The good part, the bodies of course are real. The information and commentary make you think really hard about over-drinking or smoking. It is not for the faint of heart. You will see fetuses. The bodies are preserved well, you will be in awe in just how they were able to separate the veins from the skin. The bad, I guess I wanted more. I expected to be there for 3 hours but it only took me 1.5. When we were finish I was thinking 'this is it?' I think I was also expecting weirder bodies (think Mutter Museum in Philly).
Overall, the exhibit was pretty straight forward (healthy lungs/bad lungs, good heart/bad heart, etc) and I would recommend anyone to visit it. I went on a Tuesday morning so it wasn't crowed which was perfect. When they add the weirder stuff, I'll be back.
