All sessions will be in the Stata Center, MIT building 32. This is the big wacky building that looks like a pile of blocks falling over. It's not as confusing as it looks, honest. See map below; entrances are marked.
NarraScope sign-in and information will be outside room 123 (the big room).
Here are directions to MIT by various means.
For travel and hotel advice, we'll point you at MIT's advice on accomodations.
