You can shoot a machine gun! I was all over this place when I heard of it. And it does have a great selection of guns to choose from... more than this guy has heard of. You can even choose full-auto or semi-auto on some guns.
The options to bypass the line for extra money is annoying. It's already expensive enough, tacking on another $50 or $100 is not really justifiable for some bank accounts. So you get to wait in line... Which can be a while if other people ARE paying to get ahead of you.
I also think you should be able to see the guns before you choose them. And there should be combo options without pistols.
So all-in-all it is fun but maybe a bit too many negatives to ever do it again.
