Okay, I admit I'm a little clueless on one thing: I didn't realize 'Cuse was private. Also, is Maryland giving you reciprocity or something that its not out of state? Your location is NY so I'm a little confused -I only started to fathom reciprocity agreements when I moved out here to MN (we have agreements with Wisconsin and the Dakotas). CA has no such agreements with neighboring states.
However, you said the magic words for loan repayment: Law School
(I would've also accepted "Medical School" or "MBA")
Sounds like your parents fall into that frustrating category of "too rich for substantial need-based aid, not quite enough to foot the bill to a private school". I assume you've already heard from all the schools you're in at regarding financial aid (and they probably weren't all that hot).
Rethinking things a little bit (considing what you just mentioned), you have one definite plus argument in that you're, theoretically, going to be a lawyer and will be able to pay back some of these loans -
however (and this is a big however), you may want to conserve that argument for when you get into law school (because, let me tell you, you're going to be wanting to go wherever you get in -money no object).
In the short term you probably have made the best choice considering the circumstances. College can be fun almost wherever you go.
Again, I know two cool guys who went to Binghampton and enjoyed it. Both go to my law school and both said its a little quiet there but nothing that keeps you from having a good time. Actually, the two of them are very different people -which is a good sign since that means you can probably enjoy it regardless.
Maryland will be the big school environment. Its a little easier to get lost in the shuffle, but there's a lot more to do.
While Maryland is a "better" acadamic school, they're close enough academically that if you do well at Binghampton you'll be just as competitive as a Maryland grad (remember, the key to getting into law school is getting a good GPA and getting a good LSAT score, all else is secondary). Also, study abroads can be the most enriching months of your life. If Binghampton makes it easy and relatively cheap, that may make up for anything you find annoying with the school. Think of it this way, you spend a year or two in Binghampton, think to yourself "not bad, but I'd like more excitement" -so you then spend the next semester to two years in London and Berlin (I've known people who did two to three back-to-back study abroads because they were smart about the applications). I think you have the right mentality with the whole study abroad aspect.
Since they're both your waitlists, I think they're the both worth going to if you get off the list.
Remember: go where you feel comfortable. When thinking about what makes you comfortable, remember to look for the things you enjoy in your free time and whether they're available around the schools you're looking at.
If you haven't visited these schools in person you should strongly consider it. I remember visiting UC San Diego and then doing and about-face on wanting to go there. Same with UCLA. When I was entering undergrad I got into and ranked my choices (1) UCSD (2) UCLA (3) USC. Then after visiting all three I went to USC.
[EDIT:
Remember: If you pick a school and end up hating it, you can always transfer.]
i learned pretty quickly that college is a farce.
