<p>My guess would be that either an overnight stay at both (I know GT has overnight “Connect With Tech” sessions, you could probably find a similar program @ UIUC b/c it’s also such a big school). I’m sure a day tour would be good enough, but if you could do overnights, that’d give you a good idea…and hey, if you are miserable, you stick it out the rest of Freshman year and transfer.</p>
<p>You can’t really make a “wrong choice” when deciding upon colleges. There’s no way you can know after a visit which school you would thrive at more. It would take a month of going to each to get a better idea.</p>
