If you don't get a formal internship for the summer, I suggest you try to build something useful that you could show a prospective employer. Given your background, this will probably be a web site. Two and a half months is enough to build something real.

Does either of your side projects solve a real problem that people have?

If not, look for some sort of frustrating inefficiency that you or your friends at school run into all the time. Then build a solution.
