People who have used them:
For anyone who shoots guns, you'll obviously recognize the fact that their pricing is a bit ridiculous; if you don't shoot guns... their pricing is a bit ridiculous. At least here in Tampa where I'm located, I can go to one of several local ranges as a non-member, buy a one-day membership for $10 and rent one of typically 30+ semi-auto hand guns or revolvers for $10 an hour. You can shoot as much ammo through it as you like with the only catch being you have to buy the store's ammo, but even then it's $13 for a 50-count box of 9mm for example; a far cry from $25 to shoot just 20 rounds through one gun.
So why would you go to this place? Obviously the fact that you can shoot a fully automatic machine gun or some semi-exotic rifles you won't typically run into or be allowed to shoot unless you have a friend who both owns the guns and has the relevant license. Even though it's pricy, it's worth doing for the machine guns alone just to get the experience.
They do have some VIP packages that let you pay a much higher one-time fee and shoot a wide variety of machine guns; or you can pick and choose.
Good place to start a bachelor party too; shooting machine guns. Obviously not a good place to end a bachelor party; machine guns and booze don't mix well.
