<p>You could easily stay at a hotel with free shuttle service to & from the airport. You can check as to whether SuperShuttle or other shuttle service would take you from your hotel to the hotel. Likely the hotels walking distance of USC are already sold out for 8/21. Would call SuperShuttle and its competitor PrimeTime Shuttle to see if either will pick you up from your hotel to take you to USC or if you have to catch the free hotel shuttle back to the airport. It’s only a 15-30 minute shuttle ride from LAX to USC.</p>
