I've never been to any others so I can't really speak from experience.
I know we built our park and it was nice and still is but it seems like we sort of didn't do much else after it was built and a lot of schools have been building new facilities.
I've always thought that the area between the stadium and the river should be developed so that there are some outdoor plazas and restaurants in that area.
What a great place to hang before and after games- and even when there are no games scheduled.
I will say watching this video- you can tell it's in need of some improvement.
The lighting is dim, and lots of low ceilings and smaller rooms, lots of hallways- sort of the style 10-12 years ago but the style now is large windows, very high ceilings, lots of large open areas and not so many separate rooms, LED lighting with bright rooms, lots of big screen video boards on walls, etc.
