If I could give one piece of advice in regards to tuition and loan concerns it would be this: attend the best school that admits you and let the money stuff sort itself out later.
A few thousand dollars (or even $30-40K if it comes to that) is a drop in the bucket compared to the boost in earning potential over the next 30-40 years of your career. Those of you who are 100% GI Bill + Yellow Ribbon will be in a better financial situation than any of your classmates who aren't independently wealthy or getting their MBA on McKinsey's dime.
I had substantial scholarship offers from two other highly-regarded schools and turned them down to attend HBS even though I wasn't Yellow Ribbon-eligible given that I only qualified for the 80% GI Bill rate. Even with me opting for a lower-paying job than 98% of my HBS classmates it's been no issue making the monthly payments on the $20K-ish of loans that I took on.
