Best parking option?

If your in the area walking or a taxi or uber are very easy for in and out. There are a couple of affordable parking garages near by

They will validate your parking, but only in one garage and only for a limited time (I think It's 2 or 3 hours). Check with them to be sure you have the right parking garage to get the validation.

Street parking, if not there is a garage close by and a short walk

In a pinch a reasonable walk from the Boston Common garage

Really depends on how busy. I did a few loops around the block and found parking but was middle of summer and place was packed. I like freedom of self drive, but Uber or cab away

Best to uber or lyft

Uber
