I should have visited Princeton a lot more when I was in highschool. I'm not sure if I would have been accepted or attended the university but I look back and regret not applying. The school is put together extremely well in a manner that seems conducive to increasing learning. The other Ivy League schools just don't compare in terms of beauty and tranquility.
There is more to Princeton than the University. There's a small "downtown" area that has several decent restaurants and Small World Coffee is a good spot to grab a hot drink before or after dinner.
