(10 Points for Best Answer) Big problem, does anyone know what I should do here?

I think that you should definitely ask around for her number. Honestly, it does seem kind of creepy, yes, but I'm sure that the "creepy-ness" would go away after you tell her the situation. I know if a guy contacted me telling me this, I would love to hang out with him and be flattered. Go for it, don't risk not seeing her next year.
