How does a time-lapse during UG affect MBA apps?

I posted this in the Q&A with consultants from Accepted, but was curious if anyone else has a similar experience and could contribute. I'm new to the site, so please let me know if I'm doing anything wrong.

Hi Natalie & Jen,

I went to a semi-target for 3 semesters before taking a break to get my financial house in order (took about 6 years) and I'm now back at a non-target finishing my UG in Fin. My grades 6 years ago were not great (about a 2.5 GPA) but my cumulative at my current university is a 3.9.

My question is, will a top-20 school completely disregard me because of my transgressions 6 years ago, or will they see someone who got his act together and finished strong?

I know WE/GMAT are very important as well, just wondering what the admissions will think of my transcript.
