<p>Interviewing at two schools a day is totally doable by scheduling the first at 8 or 9 am and the second 1or 2 pm. Expect to spend about two hours at each school.
We interviewed at 9 schools in one week with Sunday to rest. We ended up driving over 1400 miles (> 2300 km) visiting 7 states in 7 days (preceded by 7000 mile flight by the student.) Your list of schools covers “only” 4 states, so involves less driving. It’s certainly not for every one. The driver (moi) was willing and the student was cooperative. I wouldn’t do that again though.</p>
