Rory was a wee bit hypocritical about not wanting a party in her dorm at Yale.
Paris actually asked her. Lorelai didn't bother asking when she invited everyone into the dorm for food on their first night at Yale. They didn't bother asking Tana either who was clearly awkward around people and might have been uncomfortable with being abruptly ambushed by so many.
Rory needed her mommy to cope with being away. What if the other girls had anxiety too and just needed to be alone?
And then when Paris actually considers her and asks her to have a party in the dorm she says 'I might be tired that night. I don't know how ill feel.' Well don't you think people who spent the entire day moving boxes into their new home might also be tired?
It just bugged me so much.
