We're staying near the Burlington Mall (family of 5) and thinking of a trip to the Science Center and maybe into the North End for dinner. Should we drive from Burlington to the Science Center, since they have their own parking? Or, should we drive to a metro station (which one?) and then buy tickets for 5 into the Science Center and on? We could do this on either a Friday or a Saturday as sometimes day of the week influences congestion at parking garages or metro lots. Thanks for the help!
