<p>I’m not sure about Kenyon, so I can’t really provide you insight on that.
But I lived in Ann Arbor, Michigan, and my parents were graduate students at U Mich, so I’ll tell you what I’ve heard 
For U Mich, expect your classes to be huge (at least, for economics). My parents told me it takes more than 30 mins for roll call. Your classes will be (mostly) taught by TAs, your tests will be graded by TAs, and your questions will be answered by TAs. Now, this isn’t to say that U Mich faculty don’t love to teach; its just that some are more concentrated on conducting research/testing out theories/publishing papers. This makes U Mich an excellent school for graduates (this is my parent’s opinion) but not so much for undergrads who really want to hone their academics. U Mich, however has a lot of school spirit, fabulous location (Ann Arbor), and a ton of people to meet (It is in the Big Ten). Go Blue!
With the urging of my parents, I applied to Swarthmore. The campus is gorgeous, but I’d say there’s a lot to do in Ann Arbor than Swarthmore (in terms of walking distance). But don’t ignore opportunities at NY and Philly. Swat only has undergraduates, and the professors are amazing. You can easily change your major, your classes will be small, so if you plan on skipping classes, this school is probably not for you. The cliche saying goes, your professor will know your name.
Anyways, have fun choosing!</p>
