Is there someone who can make some of the trial trips with you? My son is, of course, a lot younger than you, but he likes having a comfortable person accompany him on test drives.
You should also explore a little around campus ahead of time, checking out places to eat, making sure you know where all the classes are, etc.
Good luck!
