my ds is an RA and has lived in the dorms at SIU for nearly all of his 4 years. He ventured off campus last year for one semester... and actually missed living in the dorms.
Some of the things he has mentioned ... to kids wanting to pick a dorm...
1. Check the dorm out.. visit campus... talk to people who actually LIVE in that dorm
2. Location... Location.. Location... do you want to be near classes, near town, near the gym, near the student center????
3. Check out crime activity for that dorm. Yes, this changes from year to year... but it does seem that there is usually one dorm hall that has more criminal activity than the other buldings. You can ask/call the local police dept for the university.
4. Dining facility... while visiting have a meal at the dining hall that serves your top choice dorm.
5. Co-ed, single sex, all freshman, study floor, major floor (ie: ROTC vs communication majors... totally different styles )
6. Communal bathrooms, shared suite bathrooms, single room bathrooms...
7. Parking... cost? .. is it a half day hike to the lot from your dorm?
I am sure the Univ. of Ten. will set us a visit to all the dorms when he visits the campus. I know SIU has all kinds of info and pictures on their website. I would think UT would too.
It helps to know his likes and dislikes... but those may change when he gets to college. And that is OK.. It is part of growing up.

Btw.. I know there are lots of kids from this side of the river that go to UT..and I bet there will be some kids from your community that will end up there too.
Best wishes!
