<p>I saw the double waitlist situation come into play once, a few years ago. Young lady at son’s school who was a talented music type was waitlisted at several selective LACs. She cleared Middlebury’s waitlist, accepted the spot and very soon afterwards was offered a spot at Swarthmore, which was her first choice all along. The school had no problem with her accepting Swarthmore and letting Middlebury know the situation anymore than they did with her declining her initial acceptance when Middlebury came through. But in her case both acceptances came after the May 1 deadline. I never heard of anyone clearing the waitlist before May 1.</p>
