I have been to Maryvale Baseball Park the past two years during spring training and I really enjoy this ballpark. The ballpark is smaller so there are good views regardless of where you are at in the stadium. The most recent spring training I had seats towards the back of one of the sections behind the home plate area, and there was already shade by the time the game started. People have always been friendly at this ballpark.
Food options are pretty good, lots of hot dogs and sausages offered. They also have items like kettle corn and Italian ice.
I think that the Brewers are one of the only, if not the only, team to have some days in which they give away promotional items during spring training. I have yielded two bobbleheads as a result.
