if you like Wellesley I would go for it. I have no issue with turning down Cornell for it- it’s got great prestige itself to anyone who matters and you seem to prefer it’s LAC environment. there doesn’t seem to be a question here. will there be people who think you are nuts for turning down an Ivy League school? maybe- but they are ignorant.
it’s going to cost you 32k more over 4 yrs than bowdoin and 24k more than cornell. to me those are not dealbreaking numbers.
