Seems like everyone is on the right track in this thread, but I'm weighing in anyway because I hope other people see this - we get questions like this from client all the time, so it's obviously a pervasive issue. As a former admissions officer, I can say that no professional with any pride would cede decision-making control over to the person who merely "wants it the most." This is to say nothing of the fact that most admissions offices do not have robust CRMs capable of tracking (let alone qualifying) touchpoints. In fact, the very reason that people believe you "have to visit Columbia to get in" is because Columbia asks in the app about whether you have visited and the reason they ask is because that's really the only way they can find out how many applicants, admits, and enrolled students visit before they apply. As with many other aspects of the application itself, the question is being asked more for data acquisition than it is for evaluation. These are the types of myths and untruths that spread around the Internet like wildfire. Ask yourself though: if you reviewed files for a living and prides yourself on identifying the best applicants, would you ever give bonus points to people who visit the school?
Furthermore, the schools who really want you to visit (like Tuck or NYU) will ultimately have tools to either encourage or require a campus visit. Nobody is looking to fool candidates, that is for sure.
If you can, you should visit the school at some point, but that certainly doesn't have to be in the midst of a stressful period in your life, on a short time line, or when it's bad for your budget. My advice is to see where you get in and then visit those schools - better to spend time/money visiting maybe 2-3 options once you are admitted rather than 5-6 when you are applying. (Final note: I accepted enrollment, attended, loved, and graduated from one of the top five law schools in the country without ever laying eyes on the place first, so even if you can't visit, it can still work out.)
