<p>As a veteran of the 4 hr each way college drive, this would be my plan:</p>
<p>Day 0, Drive S1 to College 2.5 hrs away.
Stay over, unpack in morning of Day 1, drive home.
Meanwhile, S2 has packed and readied for the trip on Day 2.
Day 2, drive S2 5 hours. Unpack. Stay over.
Drive home on Day3. Perhaps stop and visit S1 “on the way”.</p>
<p>I would also allow the S-group to help with the driving. </p>
<p>I think my issue is that I have more money than energy for driving and moving. Your mileage may vary!</p>
