Anyone been to a concert at MGM Grand Garden Arena VEGAS? what are the best seats for the best view of stage?

I have tickets for the Coldplay concert at MGM Grand. I have floor seats for section F midway (back left area of floor section) and also have seats in section U12. I want to give one set away and keep the best set for me, but I don't know if the floor seats will provide me with a good view or the other ones would be better. I want floor seats but I'm afraid I won't be able to see with people in front of me.Anyone been to a concert at MGM Grand Garden Arena VEGAS? what are the best seats for the best view of stage?
Check out the MGM Grand Web site and look at the seating for the Arena. Personally I like the seats right against the rail where no head is in my way.
I'm a short, five foot tall woman. In my short person's opinion I would rather be upstairs in U12 than section F any time. Once the show gets going and people stand up... I can't see a thing! Section-wise you're actually about equal distance from the stage, just higher up by 2 sections. So the band will look smaller than from the floor seats. But you will see everything. Below U12 is L12. If you're fairly tall you may want to keep the floor seats.Anyone been to a concert at MGM Grand Garden Arena VEGAS? what are the best seats for the best view of stage?
Never been there. I would rather to go to LV to gamble and see the "B" shows at a cheap price that later become "A" shows at a price that I won't pay.
