Parking recs when needing to arrive 4 hrs for pregame tour before Saturday 6:10 1st pitch?

Right now my plan is just to find somewhere within walking distance but it's really not obvious to me what would be a reasonable price and distance to expect. I'll be coming south from 45 and then leaving west on 10 if that matters at all (probably not). Event-based parking kicks in at the wrong time since we have to be there 2 hrs before gates open. Don't really know if I should be looking for street parking, lot parking, or a garage.

Sorry if this is a repeat question. I didn't really find anything definitive in my search. Any help would be appreciated.
