Digging this back up. Thank you all for your experience and suggestions!! I texted all the details to my wife for reference. I booked RT tickets from SAN to BOS arriving 14 October and flying home on the 19th.

I was thinking to rent a car for the duration but as many said a rental is NOT necessary in BOS. Regardless a 1 week rental car is near $1K for October so that is not happening.

Both cities we are centrally located lodging wise (hotel and AirBnb). We will be mostly walking or public transport in BOS, maybe some rental bicycles in NP. Transfer between BOS and NP looks like it will be Uber.

Anything else you folks can suggest would be appreciated. Again thanks for all the feedback!
