I’m also always in the camp of letting the student be the driver of this decision based on what she enjoys and wants to do, not based on if it can help her get into college.
There are thousands of schools in the US that would be happy to have her based on her grades.
Also, if she gets an ACT score of 33/34, that is the top 99th percentile and would be an excellent score. High enough to not have to retake.
Lastly, there are some fabulous academic DIII schools with ski teams - Bates, Bowdoin, Colby, Babson, Middlebury, etc…
