Graduate School Rut

Hey /lang/, I am a Modern Foreign Languages major, and I graduate in 2010.  I have only gotten to study Romance languages, and I realize that I kind of like the technical aspects of the languages more since I took Latin class last year.  I wanted to know what academic windows of opportunity I had with my major regarding the selection of a graduate school program.

The problem is that I have no time in my schedule for a double major.  The only way a double major would work for me is if I graduated in 2011.  My major problem with that is that five year seniors from my idiotic school lose most of their funding, so I would be royally screwed because my school costs $30,000 per year.
