despite catching the 6am megabus to new york city, it took us 6 hours to get there because our bus broke down midway. that meant we only had 6 hours to roam around the city before catching the 6pm megabus coming back to boston. our bus didn't break down but we spent an hour and a half stuck in traffic because of an accident. we didn't arrive in south station until midnight, 6 hours after we left manhattan.
