I normally get the bus from Logan to Providence when I visit. This time I'd like to get the train, as it's much faster. What bus takes me to South Station from Logan, can I get any bus, do they all stop off at South Station?? I will have a large suitcase as I will be on holidays, is this possible by train? I normally sit on the bus for 2 hours and don't have to worry about moving 'til the last stop at Providence Plaza! I'm well used to Logan but always like to have my bearings well thought out before going somewhere new like South Station. Any advice would be gratefully appreciated, thank you.
