This question was asked about a Royals/Astros ALDS game in 2015.
Please review our SRO page at Kauffman Stadium for general information and photos.
You'll want to be in line early so you can enter the stadium as soon as the gates open at 5:00 pm. Once you enter, you'll want to know which area of the ballpark you want to target. There are standing areas behind many of the outfield sections and the ones in right-center and near the Fountain Bar are most popular. If you're there early enough, you shouldn't have to run to secure a spot.
General parking is $20 for the 2015 ALDS with prices rising to $25 for the ALCS and World Series should the Royals make it that far.
