Awkward to reapply?

<p>Applied to a summer program last year, got in, but was unable to attend. I sent an email thanking and declining the admission offer.</p>

<p>This year though, would really like to attend. Since I declined their admission offer before, is it a bad idea to reapply? Is there a chance my application would be rejected based on "past statistics" of applying and not attending?</p>

<p>I have no experience but I doubt if they will notice you applied before. I think they don’t have time to do that.</p>
