Parking totally sucks. But if you smile real nice, the cute co-ed who staffs the parking booth in front of Sage Hall might give you a free pass to the (somewhat) nearby parking structure. At least, that's what happened to me. She even told me she wasn't supposed to. That, folks, is the power of my allure.
Other advice - make nice to Michelle, who you'll meet when you come into admissions. And I hope you don't get the same schmo running the info session that I got. Total doofus.
And....if you have time, walk yourself over to the Johnson Art Museum. It's a big square building perched on the edge of the hill. Go up to the 6th floor and look out the gigantic windows. Best view in the county. The art ain't half bad either. But the museum is closed on Monday. Also, make sure you get off campus. Collegetown is a little --- well, undergrad-y. The Commons is lovely, and at the center of downtown Ithaca.
