I see what you mean about the road to Sunset, I went through there a few times... I can't remember going along much pathway though, lucky I was on my bike at the time.
OFT's location is far easier and I suppose safer (In a way) Just one straight road, Dyer Blvd... that has street lamps and paths. The pupil housing is right next to the school, the recommended Hotel (The Sheraton 4 points on 192) is only about 60 metres away from the turning into Dyer Blvd.
I also agree that you should stay in the school's residential area (Like you said), I don't know how you would be able to get a hotel room at 17 anyway as I was unable to...
The student housing was perfect anyway and cheaper of course!
