I see your point, Adam: I don't want to date the sister of the girl of my dreams either!
That said, having been through business school, I actually think that most people could be happy at a number of programs. I went to Wharton, but I believe I would've had a great experience at Sloan, Tuck, Kellogg, or Stanford, among others.
And, to complete the analogy, it depends on your philosophy, there might be multiple "girls of your dreams" out there!
In any case, there is no perfect approach. If you firmly believe that this is the one place for you, then who am I to tell you otherwise! Just know that, of course, it is a riskier approach than applying to multiple schools. That's all.
Best of luck!
