<p>You could do the one parent trip for reasons described in #14. It makes a lot of sense. </p>
<p>But our family opted to do a trip with 2 parents and junior hs son (w/o older sis) for spring break junior year. We made it a combo trip of pleasure (3 days in San Diego) and 3 days of college touring near LA (Cal Tech, Pomona, Harvey Mudd). It was really great because we had a lot of time to talk about college, away from the pressures of schoolwork. Yes, it did cost more money to have both parents. But we do most vacations visiting extended family, and this as a nice change of pace for us. </p>
