KillarneyRose,
Yes, girls definitely do this. I know several from my college who only went to my school because it was easier to get into a sorority there (not as many girls went through Rush compared to the numbers going through at larger schools). They got into the sorority they wanted, and then transferred after initiation to UGA. To me, that's a little over the top, and I wouldn't have ever even thought of doing it, but for some girls being in a specific house was their top priority at college and they would do whatever it took to get there. Hope this answers your question!
DZ Love,
Carrie
