First rows available on the concert day?

[Villavic]

Ok, here is my issue. I got my ticket for Dallas april 30, the best seat I got on Ticketmaster was a rear left floor, like 30something or 40 row. I'm flying from Peru on wednesday night, arriving in the morning at DFW.

I'm not happy with this seat, so I've tried with no success to buy a platinum seat, but neither Iloveaccess or Livenation/Ticketmaster accept my peruvian credit card. don't know why, it's first time I can't buy a good seat through internet because of being foreign.

I've tried several times, since aprox 2 months ago. Even now that I see better prices, and ticketmaster chooses me a good seat (row 3 in a left section) , I can't finish the transaction, telling me problems with any of my 2 credit cards (amex or visa).

Question, is it possible to find a good (platinum) seat the same day buying at the window? I guess this is a question por people who has been in more of one concert of this tour. Of course I'm asking about just probabilities. Let's see how lucky I'll be.

Within the first 10 rows, I'll be more than happy. Within the first 15, satisfied.
