We ventured to Maryvale twice during our Spring Training adventures. It was #1 and #5 of our 6 games last week, seeing the Brewers play the Rangers and A's respectively. And yes, I too have not seen that many bathrooms in one place either. It is something to be commented on. We bought bleacher seats the first game but wandered around and sat on the grass on both sides of the stadium. The second game we bought lawn seats but sat toward the end of the bleachers near the third base bull pen. The attendants didn't look at tickets, unless of course you were trying to sit behind home plate. That might change as more fans make their way to Maryvale.
They bring out the Sausage Race before the 7th inning stretch and have the sausages available for autographs after the race in right field. I'd only ever seen them in the highlight reels, so it was fun! Be sure to get there quickly though, the volunteers will cut off the line because, as we were told, "They can't stay in those suits all day!" We even saw one of Brewers hit a home run right through the open square in the hitter's wall in center field. Hoped he would get an extra point or at least win a stuffed animal as he crossed home plate.
Beer selection is minimal and food is pretty basic, although there is a BBQ stand in the patio behind home plate along with funnel cake and kettle corn.
