Is November a good time to visit AZ? I might scrap the Roadrunners game and focus on the Yotes. I have vacation time I'll need to use up before the year is over.
Spectacular time of year to visit. But you're going to need a car to get around PHX, so it's pretty easy to get down to Tucson anyway, so I'd recommend you check out both, even if you just go to Tuxon for a game day. Get down there by 1, eat, check out the Titan Missile Museum or Saguaro Park or Sabino Canyon or the Sonora Desert Museum. Couple hours there, dinner and a Roadrunners game and you can probably make it back to PHX the same day.
Is that atmosphere at GRA pretty good that early in the season? I'd prefer to catch a game against a team without a huge transplant fanbase. I'll be going as a full on Yotes fan.
Weekends, sure, week nights against a so-so opponent, it'll be quiet. 10 Nov vs WPG, 12 Nov vs BOS, 19 Nov vs SJS will all be good. 3 Nov vs NSH it will be a morgue at GRA.
If I were to stay at a hotel near GRA, would driving to Phoenix be a pain? Is there a decent social/nighttime scene in Westgate?
Outside of rush hour, on the 101, it's probably 25 minutes from GRA to downtown PHX (Central / I-17 / I-10 area). Add 10 more and take the north loop to get to Old Town Scottsdale from Westgate. Your call I guess, but for many folks 25-30 minutes is usually right about the point where driving becomes a pain.
Game nights it gets super-crowded at Westgate, non-game weekends there's a good crowd, but weeknights without a Coyotes game it's really quiet there. A lot of bars and restaurants will do good specials and discounts on those nights, but it'll be a thin crowd.
