Many MBA programs require work experience as well. I worked for a few years before I went back for my MBA. It was really worth it. My discipline and study skills were so much better. I flew right through in 2 years, working a day job at the university, and stripping on weekends and holidays.

You've already made your school decision, so I'm giving you feedback for the future. I never took anytime off from school, I even finished high school early and got my undergrad at 21, taking summerschool each summer. Perhaps a few breaks might have been valuable.
