Dont really let the campus or the dorms decide where you want to end up. Think about the type of people there, who would you get along with more? because those are the type of people that you will generally be dealing with for the next 8 or more years.
Think about what type of degree you want to major in. That is what the academies are there for, to get you a college degree while training for the military. The naval academy is very technically oriented.
Also think about which service you would like more, since the navy is more technically oriented, it would probably be a better choice for an engineer if thats where your headed.
I wouldn't really base the decision off who is "squared away" more. Both academies are great schools, and the people that get accepted are great people, and get their stuff done when they need to. So the officers that are commissioned are top of the line.
Or..... you could just put everything i said aside and just GO NAVY!
Congrats on your nominations!!
