The west side is pretty simple. But you need to know your section.
If you are going to Hall of Champions area, you won't need an elevator. If you are going to upper deck on west side, go to Gate 3. That's the 50-yard line gate on west side. There is elevator there. The elevator line will be ONLY the southernmost door of the twelve doors at Gate 3.
If you are going to Field Club seats, you need to go to Gate 2 on west side. Entrance will be about the 10-yard line on south endzone, on west side. I can't remember the section numbers for this.
There is another set of Field Club seats on west side. Entrance will be around the 10-yard line on north endzone, on west side. That will be Gate 4.
Find a Best employee with walkie-talkie or a Boy Scout. They will take you where you need to go. Find them before you wait in the wrong line for 45 minutes.
None of the 4 corners have an elevator. Southwest Tower, Northeast Tower, etc.
