Tour on your own - but make sure the battery works!

Great 2 hours of looking on the inside of the stadium. Slightly disappointed that our tour was led by the headsets. There was nobody telling us about the stadium at all. Battery went on my machine which was replaced when I went to a lower floor, but still, paying to find out about the stadium but having to walk down and through the stadium to ruin what I was about to see, well yeah not great. Enjoyed being there but not the supportive set up. Could have watched a video at home instead of being there.
