Trying to figure out the cheapest trips that other's have been on.

from my own experience, my cheapest has been to El Paredon Guatamala for a week
flight 320$ roundtrip from BWI
7$ a night
15$ food/beer day (more than enough)
140$ airport pickup round trip
I went in the spring.

If anyone has had any cheap trips that they want to share, so I could possibly get outta the frigid atlantic for awhile that would be appreciated.
