Is on-campus parking open (free) on the weekends?

Will be in Chapel Hill in a few weeks on the weekend to look around the campus. Can we park on campus as we’re touring around to the stadium, Dean Dome, dorms, Old Well, etc.,.? Would rather not park in a garage or one of the parking decks as we’ll have a handicap “visitor” with us (and handicap parking pass) and she can’t walk more than a few hundred yards from the car.
