I purchased my ticket through groupon which I would highly recommend because paying full price for this exhibit would be a waste of money. I have watched the show CSI but it was many years ago and you don't have to be a fan of the show to get some enjoyment out of this exhibit.
With all that being said I would give this exhibit actually 2.5 out of 5 stars. It's located in the MGM wasn't that hard to find once you enter the exhibit and pay which is actually in the overpriced gift shop you are given your color coded sheet of paper and go and watch a video and work on your case.
The case was pretty fun to work on and it was interesting working with all the different items to crack your case. I did have a good time but I do think it is a little pricey even with the groupon and it's a down right rip off if you are paying full price. It was a nice way to kill 30 min. or so.
