Summer Program (pre college vs community service abroad?)

<p>I'm a Junior in hs and i have done nothing for any summer during my High school career. i was debating many options
1) a pre college program at BU or some where else to get some college credits but also for the experience at the college/town around it
2) a leadership program like NSLC
3) volunteer somewhere through a program- Rustic Pathways most likeyl</p>

<p>My question is if anyone has had an experience similar to any of those and would express feedback to help make my decision.
*side note- money IS a factor, so if the experience was worth an escalated price...or if something was inexpensive that i should be aware of.</p>

<p>Thanks!</p>
