Sarah lead Ned all the way back to the dorms, it wasn't a long walk and along the way she mentioned a few other points about the Ren Faire and what was in what direction. Just in case Ned wanted to explore on his own and not get lost.
When they arrived she pointed him in the right direction of the F Dorm, and reminded him that his room number was on the Key. She smiled and waved as she turned to leave.
"If you need anything, I'm in room 239 in the A dorm." She figured Ned might have more questions and she'd be opening the answering the ones she could later.
