The Summit will be at the MIT Stata Center, near the Kendall Square T stop in Cambridge, MA.
A floor plan of the first level of the building. We're in the two green rooms in the very center, with opening/closing in the auditorium to the left of this image.
To get to where we are- walk around the building until you find this door facing main street:

Then walk through the door marked Gates building:

You'll see an information desk (under the giant question mark), which should be manned all weekend:

Walk towards this desk, go past it, and then you'll turn slightly right, ending up in this hallway, where our rooms are. You should see giant chalkboards with more information about schedules, food, etc. in this area- you can see one (a large black wall surface) in the right-hand side of the picture.
