My piece of advice would be to really commit yourself to these schools. That means to spend a lot of time with your essays to make sure you have a polished and clear story explaining who you are, why you need an MBA, and why an MBA from that school is the logical next step. You really should visit the schools and sit in on classes. You should go to info-sessions and talk to people. If you can find a way to differentiate yourself so that adcom, current students, etc. all know how excited and gung-ho you are about the school, they will have a much harder time turning you down. If you present yourself with a weak set of essays, lifeless interview, no word of every visiting the school, etc. they will likely just ding you and pick another person who has demonstrated enthusiasm.
Put yourself into the shoes on adcom...you would pick the energetic, confident, down to earth, cool, humble, polite, and appreciative guy with good stats over the aloof person who comes in with the attitude of "you guys are lucky to have me and if you convince me, i might decide to go to your school", etc.
Good luck everyone on the WL. I know many students who have a lot of luck reapplying because the reapplication tells adcom that they really really want to go there.
