Harvard University summer program for college students-Is it worth it?

I am an undergraduate student at a top 50 liberal arts institution. I am thinking about attending Harvard University’s summer program as a visiting student. My reasons for attending summer school at Harvard is not only to take courses that will transfer to my home institution but I also want to “experience” Harvard. Also, instead of doing nothing over the summer, going to Harvard summer school would keep me busy. I do not have a problem with tuition, the only problem is if it is worth it? I do not want to frivolously waste money just to attend summer school at Harvard. Can someone who has attended Harvard’s summer school give me their opinion or review of it?
