After a few miles, you cross Highway 10, later Santa Monica Blvd. Shortly later, you leave 405 at Wilshire Blvd direction east and you will enter Westwood. Shortly later, you turn left on to Westwood Blvd. After about 1.5 miles you reach a parking booth where you ask for a parking sticker. Better, of course, to park your car in your hotel.
All hotels are within walking distance from the campus.
All hotels are in Westwood. Mention your affiliation with UCLA, otherwise the prices will be more horrendous. You should make reservations well in advance to be sure of getting a room. Close to campus, very new and comfortable.
