Summer Program Abroad- Help Please!

<p>I'm looking for a cool summer program that will take me abroad and possibly do community service (or an internship). I've been looking at the Nat Geo Student Expeditions, and I was wondering if anyone has done one of the trips? If so, how was it/was it worth it, and most importantly, was it expensive? Or does anyone know of other summer programs that include going abroad?</p>

<p>bump please</p>
