We will be staying in Braintree and want to take the train into Boston on a Saturday and Sunday. We did this several years ago and it worked out well but I can't remember exactly what we did. At the time there wasn't any problem parking at the station on the weekend. Is the parking $5 per day? Do you know how much the train costs from that station? Where do we get off downtown - can't remember. Do you buy tokens or how do you pay? If I remember right there was a machine at the station. Can you buy roundtrips or do you pay again downtown? Any help would be appreciated.
