Am I lacking a safety with these school choices?

After much research, I finally selected the programs I want to apply to, but am afraid these may all be too aggressive and I don't have a good safety in the mix. I'm applying to Stanford, Duke, Berkeley, Kellogg, and Chicago, any others I should add that I may have a better chance of getting in? Was thinking UCLA, but that might be a stretch too? Appreciate the feedback.

F/28 at matriculation, American
Education: Arizona State University, B.S. Marketing. Minor: Psychology. GPA 3.8/4.0

WE: 5.5 years at time of entry. Current position (3.5 years): National Marketing Manager at SuperShuttle. Create marketing and ad campaigns/manage spending for over 30 markets. Develop strategies with travel industry leaders and major airlines to jointly promote both products. Prior Position (2 years): Media planner/buyer at local ad agency. My current job is a direct progression from this one with more responsibility and on a much larger scale.

Extra-Curricular: I have volunteered with a program that brings the healing prospects of art to abused children. I have been certified as a mentor, in which I've weekly developed projects to help build the children's interpersonal skills and finding a release through art. This past year I organized a workshop on chalk art with the children and allow them to participate in a fundraiser by collaborating on a mural in front of thousands of people.

My goals after an mba is to continue in marketing, but really focus on international brand management
