>>23396864As a massfag my preferred beachy spots are gloucester/rockport and kittery maine (assuming you have a rental car). A lot of the big name famous beachy areas (nantucket, marthas, cape cod) imo are tourist trap slop; they weren't always, but they are now. By all means if you've never been to any, any are worth a visit, but it's kinda a seen one, seen em all
Theres also the battleship massachusetts in fall river which is cool. And downtown boston is worth a visit, don't try drive around down there, take the subway, you can make plans or just somewhere and wander around and look at shit for an hour and just hop back on to go somewhere else, id suggest havard sq area, chinatown, fanueil hall, prudential center; all are fairly novel wander around for ~1h stops
