Question of free ticket vouchers to concert
 

I just received four free ticket vouchers to a concert tonight at the Coors Ampitheatre for an Alan Jackson performance. On the voucher it says redeem at box office and pay $6 fee. My question is are my seats guaranteed? Can I show up a half hour before the show and am good to go?
If so, how do they determine where I get to sit?

These tickets were given to a friend of mine who works for San Diego Police Department, and they get stuff like for free all the time I imagine. So what if they give out a lot of tickets and everyone decides to use them? I think because I have to redeem them at the box office, there might be a limited number of seats, sort of like a prescreening at the movies.

Thanks for any help

I'd say it's unlikely that you have guaranteed seats if the voucher thing doesn't have a seat number on it.

But like, it's Alan Jackson, how full could this thing possibly be?
