I also thought of Middlebury, but was concerned about all of the cost, distance, and difficulty getting admitted.
A wild thought might be Bishop’s University in Lennoxville Quebec. It of course fails on the distance criteria. If you look at the cost on their web site it is denominated in Canadian dollars. Translated into US Dollars I think that it comes close to US$30,000/year, although you should probably check this. Some merit aid is possible. In our case the merit aid offered was modest, but since my daughter would have qualified as a Quebec resident this was taken off of a rather small initial cost, which I think impacted the amount of merit aid that we were offered. It is the Canadian equivalent of a smallish LAC, and has a superb languages program including a superb French program. It is also located in a small town that as far as I know is fully bilingual, and which is right next to a overwhelmingly French speaking smallish city. They also have a good theatre program (and they know how to spell it!). It is one of the three English language universities in Quebec (the other two are large). I at least think of it as far more collaborative rather than competitive. We quite liked it when we visited.
