B+
Adventure Time!
Emerson is located in downtown Boston, so there's always something to do. The reason for the B+ grade is because the trains close around midnight or 1am, so it's pretty hard to travel in the wee hours of the morning unless you feel like walking/taking a cab. However, there are a ton of places to eat, bars, diners, a few clubs, museums (the MFA is open until 10pm!), sports venues, and places to shop. Never worried about being bored. Even if you're just hanging around the Commons or the Public Gardens, it's still fun if you bring some friends along. I'd say, though, skip the clubs and find some house parties. They're always way more fun!
