As many have , I visited Hohokam Park for Spring Training ! I came the first week when the A's hosted the Angels .
I purchased my ticket on StubHub for fairly cheap. I've heard horrid stories of being cooked alive if you do not sit under the overhang so I made sure to. Unfortunately I didn't need to worry about the sun this day as it was overcast , chilly and windy haha.
Anyways , parking was $5 inside on the grass. Pull in, pay and follow the parking guy as he tells you where to park. One car after another . I feared it would be a nightmare getting out but it was not bad at all!
Go to gate, show ticket , through security (metal detector ) and you're in. Nice park, food / drinks / merchandise prices high like any other place.
All seats are decent seats. Great view and back drop. There was not a lot of people at this game and they mostly allowed anyone to sit anywhere Which was cool.
