I can think of only three issues that I'd count as real negatives:
- The overlapping timing of the Woodie Flowers Award ceremony with other events needs to be addressed.
- The placement of the confetti balloons during the closing ceremony blocked some people's view of parts of the field.
- The reserved seating for the Einstein finals teams was badly handled.
I also didn't see any reason for the large entranceway at the most convenient corner of the pit to be blocked off with a guard posted.
I do have one other minor personal peeve. In my opinion, escalators shouldn't be used as rest stops. They become major bottlenecks when people stop walking and just stand on them. If everyone would just keep moving, about twice as many people could get through in a given time.
