Are you kidding me? I must have not looked into this experience well enough opbviously! The experience was a load of crap, not challenging at all, it sucked....30, well 15 for each of us with the MGM card for what? You get all the answers toward the end anyways when you examine the body, the only thing challenging is to compare bullets and that was about it but on a scale of 1 to 10 it was 3 on challenge. Don't waste your time and money on this if you expect an experience. I expected too much like mixing with test tubes and looking at actual things that looked like blood or somewhat real, I didn't expect to sign up for a dead body in the desert and look at a small stage with a dead guy's wedding ring that wasn;t even gold, but looked like a metal, brass plated washer tool....so heavily disappointed and my dad just was in a hurry to get out of there....and certficates you ahve to pay for? This is a joke. Makes CSI unalluring, if I may use that word, which I may cause I already did.
