Does major matter once you have a SA offer in place?

I'm a junior at a non-target who will be interning at a LO next summer. Right now I'm majoring in finance, but I'm also interested in marketing and want to explore that. At my school, marketing is only available as a concentration if you get a bachelor of science in business administration. I know that business admin is generally looked down upon compared to finance, but does it make that much of a difference once you start working? For context, I would get a BS in business admin with concentrations in both digital marketing and finance.

The big thing is that I haven't been enjoying my college experience too much. It's too late to transfer, but if I go the business admin route, I can graduate early using my AP credits and use the extra semester to go on an international trip that my best friends from high school (who are also graduating early) have been planning for months. I just think that if I can major in something I'm interested in, save money on a semester of tuition, travel with my best friends, and come out with a well-paying SA and full time role, it's a no brainer. But I don't want to regret not majoring in finance and would appreciate your insight.
