Sat here for the Chiefs/Dolphins game two seasons ago when the Chiefs got absolutely killed by the lowly 'Fins. We were in row 3 so on paper, we had good seats. But in actuality, these seats suck.
Even with seats in row 1, it will be very hard to keep up with the game because you're so far away; there are three levels of seats so the fans here are at a real disadvantage. Any end zone seat in the stadium is less than stellar if you ask me and I've definitely seen my share of games at Arrowhead in my 20 years as a Chiefs fan. The seats are also packed in tightly together with no cup holders whatsoever. It's impossible to let loose and cheer loud for your team when you have to hold onto your $8 beer the entire time.

Worst of all, if you want tickets here, you're still looking at $50 a seat for most games and that's definitely not worth it and neither is the $27 for parking unless you've got a big crew tailgating with you that will chip in.
Your best friend will be the scoreboard/replay board in the opposite end zone. It's circular, could stand to be much bigger and there is one in each end zone.

Many mothers won't approve of this stadium as a place for children. Lots of bad language, and drinking, and the occasional fight. You've been warned.
