Jamaica is probably out of the price range of most college kids I would think. It seems to be a little pricier than some of the other SB destinations. (not expensive by any stretch, unless you truly want a 5 star pampered experience) However, I think Jamaica as a whole is not priced an a manor to cater to college kids.

I could be very wrong, but from what I barely remember about my spring breaks, there were packages that catered to specifically get college kids to come, and for cheap to other places.
