My son and I are arriving at Logan on July 4 for a short 2-day visit. We are staying at the Fairfield Inn Cambridge which I am told is across from the Lechmere T station. We plan on spending the afternoon of the 4th in Boston for sightseeing and then visiting MIT campus and the Cambridge area on the 5th. It looks like we will be able to use the T rather easily to get from the airport to our hotel, then to the downtown areas, and also from there back up to MIT. Does this sound reasonable? Or should we plan on using Uber or renting a car? I'm assuming as in most major cities parking/driving ourselves will be expensive and frustrating so hoping the T is as straightforward as it appears. Thanks!
