Am I an idiot for turning down a full ride to Columbia?

As of April 30 I have been committed to the University of Virginia, who gave me $30,000 per year in scholarships and $10,000 per year in institutional loans. I really love UVA and I think I would be a great fit there. My family lives close to Charlottesville and I really have my heart set on going there. However, last week Columbia admitted me off of their waitlist and today they just told me that they are giving me $74,000 a year, which fully covers tuition and some living expenses.... Am I an idiot for turning down a full ride to Columbia?
