Scottsdale is not my favorite spring training park in the Phoenix area, but it's not bad.
The only bad thing about it is that almost all the seats are in the sun. They actually have misters during the game, but only from the roof -- the mist showers those few who are already in the shade.
The location of the little stadium is really nice. Parking may be difficult, so go early, but once you park, you can actually walk to several restaurants after the game.
