Quinky, I would recommend the top category for a wealthy man like yourself! Seriously though, whatever you buy make sure it's as high up as possible in the north, east or west. Halfway up the south should be high enough. The views lower down are rubbish.
More or less, what he said.
Certainly NOT in the bottom/lowest four rows - ABCD. People standing or moving in front of you will drive you bonkers. In the East you have the prevailing wind toward you, plus possibly the sun in your eyes. In the West consider which side of the halfway line you want to be? Access to Members Bar? Leaving the ground after the game? Seat numbers 125/126 are smack on halfway.
