As people have said it doesnt matter that much where you are as long as you are there. Granted people in the Lower section have a better chance of getting on TV but we were in the Upper section in 2009 & 2010 & the atmosphere around us was fantastic (created a little in 2009 by the fact there was a few pie-eaters near us - great banter).
Having said that not sure i would like to be right at the top but the view from the first dozen or so rows of the upper section is fantastic!!
