Harvard Kennedy School vs. Reapply B Schools next year

I applied to Wharton, Tuck and HKS in hopes of getting into the MBA/MPP program. However, I was dinged at both Wharton (without interview) and Tuck (adcom initiated interview). I have an admit for the MPP at HKS (no scholarships offered). My goal is to go into development consulting (either with MBB or niche firms like dalberg, bridgespan). Plan B would have been finance (IB or corp) to payback the heavy debt. I am an international with a non traditional background (2 years entrepreneurship and 1 year local development sector), so my options post MBA will be limited and to companies sponsoring visas.

Should I wait a year more and give GMAT (used my GRE this time) and reapply to t15 bschools for the next cycle? I have 3 years work exp at matriculation now, and at next cycle it would be 4. Most importantly, I am debating whether the debt from HKS is worth it. Other option would be to give GMAT, go to HKS and apply/reapply to institutions that has concurrent degrees with HKS. What do you all think?
