davis_square | Parking for an event (100ish people) (Reply)

I'm going to be using two Davis Square locations for my July wedding and I'm wondering the best way to handle parking as neither of the venues have their own lots. My guest list is about 100 people and I'm already planning to urge people to take public transit/park at Alewife or carpool (my reception should be ending at 11pm/midnight at the latest, so the T should still be running).

I can't remember since I moved last year - if people decide they still want to drive their own car, is parking on-street and in the pay lots still free on Sunday nights? If not, does anyone here have experience with businesses letting people park outside of business hours with advance permission? For free or for a small fee?
EDIT: Ron has informed me that residential parking is free on Sundays, so I think that should be good enough for our needs.

Also, the two locations are about .4 miles apart and it's just not enough to justify some kind of fancy-pants transportation. If it's a nice day, most of the wedding party/guesst could probably just hoof it (as it wouldn't even make sense for anyone to move their car). However, we do have a few older people/people with disabilities attending and I'm wondering if anyone here can recommend an extremely reliable cab company - I would likely call in advance, the night before and then the day of to confirm pick up. Otherwise, I'll probably have a few relatives drive from point A to point B and then go back to a lot.

Thanks!
