Vanderbilt (full-tuition) vs UChicago ($15,000 scholarship) vs MIT (full-pay)

Like the title suggests, I'm pretty split between these two schools. Vanderbilt would cost be around $16,000 a year, UChicago around $58,000, and MIT around $65,000. My parents are willing to fund my college education so cost is not that important but I would like it to pay off. At Vanderbilt, I would be a Computer Science and Economics double major; at MIT, I would major in Computer Science, Economics, and Data Analysis or just Econ; and at UChicago I would major in economics (and maybe minor in Computer Science). At Vanderbilt, my GPA would likely be higher than if I went to UChicago or MIT but it's definitely not as heavily recruited. I could also more easily double major at Vanderbilt because there's no limit on the amount of AP credit. However, I don't exactly fit in with Vanderbilt's social scene and I definitely don't have as good of a personality that helps out in job/internship interviews.

My main goal is to get an internship all four years, in investment banking, consulting, etc. Could anyone speak on which option I should choose and whether I could still get a job in IB/consulting even if I went to Vanderbilt? Also, what are IB/consulting companies looking for when considering interns-- GPA, schools, etc? Thanks so much!
