The porta-potties situation should not be any worse than the last 1-2 years that everyone has already lived through so I'm not sure I understand the less space argument you are making.
I also don't think any Cytown traffic on game days will be in addition to all the people that were already tailgating. A lot of the traffic will be from people that probably utilize Cytown instead of traditional tailgating.
If I can get bottle service at the future "Elwood Lounge" and a bucket of wings
I could spend some time there pregame
