A few questions/thoughts to think about:
1) How do you know you'd enjoy working for the private space industry? Sure, it sounds cool, but until you try it, don't assume you'll love it.
2) Academics is not the most important thing. More important is getting experience. Look at the schools you're interested in and see what professors have contacts with the industry. E-mail them and, ideally, try to meet them. Most professors are very approachable and interested in working with undergrads. Sure, you'll be essentially free/cheap labor for 4 years. But you'll get hands-on experience and learn a lot, and, if you're any good, the professor will drop a note to his former students at SpaceX or whatever other company, who'll get you a job as soon as you graduate.
3) Take classes besides engineering. You'll learn a lot, meet new people (networking is the most important thing), and get a different perspective on life. And, you might decide something else is more interesting. Treat college as a chance to explore and learn, not a something to deal with on the way to what you think you want to do.
4) Male/female ratio and social interaction in general is essential. If you go to a good school, you will be battered by problem sets, projects, etc... You survive that by having friends, a significant other, etc... You don't survive that by just working harder. Having a good social life (which does not mean partying all the time) is vital for having a good college experience and being successful. Plus, you never know when your friends will be able to help you later in life. And learning how to socialize (which you're probably not the best at right now) while in college means you have the skills to be confident both for future personal relationships and when you look for a job and need to deal with other people.
5) If you/your parents don't have any money, go to a good state school or to a school that gives you a good scholarship and save >$100k. It's not really worth the hassle if you really take advantage of the opportunities in your school. And you can always work with a professor at another school during the summers.
6) If you do have the money, go to the best school you can. The advantage of those schools is not that the education is better, but that the networking opportunities are much better and that the professors there have the best connections. MIT and RPI are good. Also Cornell has a top notch engineering program (and it's my undergrad alma mater). Carnegie Mellon is very good. Also Cooper Union, UPenn, Princeton, and Columbia. Probably some others as well.
Good luck and remember, academics is not everything in life!
