Below is an aerial view of campus with the Lord Jeff Inn, the campus loop road, and Webster identified. Parking on campus can be tricky so if you don't mind parking in Amherst and walking onto campus that's probably easiest. Webster 102 is the conference room I've reserved. It's on the ground floor of Webster, on your left when you enter the building from the left entrance on the campus quad side of the building. Here's the location on googlemaps.
