For anyone on the fence about going next year, the experience is awesome. There is one person out of our usual Dota group that didn't go and he severely regrets it. Production was tight, can win free stuff, get a free gift bag of stuff, obviously meet the players and personalities as well.
Key Arena itself is balls however, older place, seats are very uncomfortable and the food is overpriced crap (churros were surprisingly good though). Food trucks outside make up for that part atleast.
My brothers are I are absolutely going again next year.
