Carleton vs. Amherst

My son had chosen Carleton (before May 1), but was recently admitted to Amherst off the waitlist. So we’re seeking advise and comments to help decide between the schools. I posted in the College Search and Selection forum about it:

but thought I’d also see what people here had to say. Thanks.

Oh, gosh. I have so many thoughts after reading your other thread, but I have to run out now. My kid did work-study, study abroad, played ultimate … all the things you wrote about. Well, except physics. No way there. I will respond on that thread later tonight. Great choices, but I have to say that I am leaning Carleton.
