In her opinion (based on 3-4 weekend visits this past fall), UTK is too much of a 24/7 party culture for her liking. She likes to have fun but doesn’t necessarily want to be woken up by drunken roommates at 2am during the week. This has been her bf’s biggest complaint - not getting any sleep during the week because his suitemates and floormates are out every night. She was looking for more of a “work hard/play hard” environment, with students who get up and go to class. Again, in her opinion only, the “work hard” part is somewhat lacking at UTK. I don’t doubt that there are plenty of students there who work hard - this was just the vibe she’s gotten during her visits there.
ETA - I’m sure part of that is doing your best to find like-minded roommates, which can be a big challenge.
Is your D considering Greek life? It’s pretty big for girls at each of the schools you are considering (although obviously not mandatory).
