Hey, I would RECOMMEND some time off! Some people go to work for a while, others travel, others do some volunteer work. As Dr. M. pointed out, as long as you have a good reason, it isn't likely to be a problem. In fact, I saw applicants this year at my school who did such cool stuff during their down time that it definitely enhanced their application!
Once med school starts, you haven't much time for anything else, anyway, so it is a good thing to enjoy your time. It's your most precious commodity, baby!
Best of luck...
