Attended a Suns/Warriors game in late 2016 - sat in the top deck. Of course Warriors tickets are like $70 when usually those seats would go for $11 against the Kings or Nuggets - I'm a Warriors fan - whatchagondo!
The arena is downtown near a ton of restaurants and the Diamondbacks stadium - I found parking across the street for $20 and splurged, You could find $10 or $15 parking withing 4-5 blocks if you're willing to walk. The staff were friendly and the arena was clean - fun entertainment in-game and the DJ was good (inspired my wife to start a "Rowdy" Pandora station - featuring Lil Jon and friends, mostly haha)
Living in the PHX area, I hope the Suns young core improves to a playoff team soon!
Also, shout out to the Suns gorilla mascot - doesn't make sense, but it totally works!
