My son also lives 5 hours away. He did the alumni interview in our local area, and got in regular decision with a presidential scholarship. After admission, he visited and they raised his scholarship offer. He is a freshman there now.
I disagree with @JonathanK about not visiting not impacting your chances- CMU’s Common Data Set indicates that demonstrated interest is “Important”- as much as essays and recommendations! While this is not limited to just visiting, OP will have to think about how they’re expressing interest- alumni interview is definitely good, but staying in contact with admissions, signing up for mailing lists, etc. will help.
