UT has excellent placement rates, as do all except THE UNIVERSITY THAT SHALL GO UNNAMED. You can very likely find a sorority home at UT but you have to be open to every last one. As soon as you set your sights on a particular few chapters, yes, you are probably doomed.
Forget the tent talk. You'll be fine.
