That's because they are few and far between. The elevators are there (I did see one), but they were "out of order" the day I was on my "tour." Come to think of it, the escalators were out of order too. Very strange becasue it was days before the Eagles Concert... but oh well... that's for another discussion. There are elevators, but again, I was shocked at how few and how much distance is between them. For a building that is supposed to be handicapped friendly, physically challenged people will find it inhospitable. The ramps are so steep you need an all-terrain vehicle to climb them and the elevators are all but nonexistant.
i always use stubhub i think it's the best gui for ticket buying. i'd avoid ebay...the prices are not competitive
