uchicago, vanderbilt or barnard

i recently got into these schools as a transfer student (rising sophomore) and is hesitating on school selection would barnard's location and columbia connection outweigh uchicago? im also considering vanderbilt since their core curriculum is easier to handle than uchicago's( uchicago's core are distinct classes, where as vanderbilt's core are just requirements in different fields. i plan on doing double major in econ, art history and a minor in compsci , so most of the core would be fulfilled with my classes in my majors/ minors) my heart is leaning towards uchicago but im worried i won't be able to graduate on time since im pursuing double major and a minor and uchicago is known for a big workload.  i have done the calculation, and technically, i will have enough space to fit all courses, but i'll have to max out my credits ever semester. plus, i also need to do internship, and is currently in an extensive art history research that'll probably last 2 or more years. 

（ im interested in private equity, venture capital, entrepreneurship, banking and the art business, and most of my current credits are in compsci and art history)
