MotoGP Aragon - Advice from anyone who went last year

[pulverizer]

I am thinking about going to the Aragon MotoGP in September because I am going on vacation anyway, and I though it might be a good combo trip to go to Barcelona area then go to the race.

Did anyone happen to go to the race last year? If so, do you have any insight on the best areas to sit before I go and buy my tickets?

Thanks!
