Scholarships, Research Money, oh my!

I've been offered a research opportunity AND possibly a scholarship of some sort (not sure yet) at a school I'm accepted at. The catch is that I'm still waiting on a waitlisted school. What should I do? If I do the summer research, then get accepted into the other school- isn't that REALLY torching bridges? Comments? What about the scholarship stuff? I haven't gotten it yet but its in the mail. Should I accept it?

Yeesh,
Meep-Meep
