Visiting colleges is crucial to making a good decision for your next four years (or less) of schooling. I strongly strongly strongly strongly encourage doing it if you haven’t already (and perhaps going again even if you have). Getting a feel for the people (administration, current & prospective students, profs etc alike), receiving information about programs and people, seeing the campus, understanding the facilities and resources, and most importantly, being able to talk to real live people in real live person, is so ridiculously important. Just like you wouldn’t buy and move into a house without actually visiting it, you shouldn’t haphazardly choose where your tuition goes and move into a college without visiting, either. (I often think about how many ultimate discs or pianos or cars I could buy with the money that’s going into my college tuition and sigh. Repeatedly.)
I highly recommend attending schools during their admit program/days/whatever fancy name they use (like Harvard’s is Visitas and MIT’s is CPW and Rice’s is Owl Days but you know, it’s fine) because that’s when you’ll meet the highest concentration of other admitted students (basically, you can scope out your potential classmates and see what sort of other students were admitted and if you think you’d jive with them) and that’s also when the school will be pumping out its highest concentration of resources for prospective students (aka more free goodies! but more seriously, that’s going to be the best time to find upperclassmen to answer your questions honestly because they volunteer to do it, and other important people like professors/admissions counselors/program directors/finaid, etc.)
Also! If you can stay overnight, do so. That’s the best time to actually see whether campus is safe at night, whether paths are brightly lit, if there are noise problems, what the dorms are like (aka are they partying hard or studying quietly heh), etc.
I’ve noticed the ability to visit colleges depends mainly on 3 things: your academic availability, your monetary means, and your parents’ opinion. I’ll advise you guys on how to work out the best circumstances for the first two and drop some tips for convincing the parentals!
