At this point the Brewers have to be one of the only teams left who do not have a premium seating area directly behind home plate. If I were them, that would be my #1 priority with any renovations. But it may come at the cost of booting out some long tenured season ticket holders (who are probably paying the lowest prices in MLB for those seats). The VIP parking/valet would surely be packaged with the above.
A dedicated family area is intriguing but an upcharge might be a tough sell, unless there is something truly unique about it.
I didn't follow the legislation too closely, but they are spending a huge chunk of the funds on maintenance, right? And installing air conditioning?
