MMH fees are not what I call reasonable.
But for your parents and because you say they don't hike, I think you will need to pay for parking at least $10, app $50 in day passes depending on how you group, and a bus fee from the parking area to the grounds proper.
Most expensive place I have ever paid to "hike". The kids loved it when they were young and the adults enjoyed it too.
You can hike in from the Preserve and pay just that day use fee - but it's a much longer walk.
