I know you say you are full-pay, but students (and parents) have been surprised before at how generous some of the most highly-rejective schools can be, even for high earners.
One of my kids went to Brown, and it sounds like it would be a good fit for your daughter and she has the grades and stats to have a chance, although of course it is a high reach for everyone. Just wanted to put it out there because families are often surprised at how much need-based aid even higher-income families can receive from the Ivies. It might be worth running Brown’s NPC just to see.
