We are driving in from down south...is there parking nearby? Free or pay?

Paid parking but limited

I found street parking once, but it's so close to Harvard Station that I just take the T from now on.

There is a privately managed parking lot on Church Street; the municipal parking lot is in front of the Charles Hotel – cheaper, but rarely empty.

There's some street parking with meters, and some pay garages nearby. The street parking is often scarce. You could also park in the garage at a T station (e.g. Alewife) and take the subway in.

There may still be discounted parking nearby (with validation). Your best bet is to reach out to the club.
