Consider renting a car to have maximum flexibility in exploring the city and surrounding areas. A rental car for 7 days starts at around $300. Expect traffic during rush hour and plan accordingly. Uber and Lyft are also available in the area but can be more expensive depending on the distance traveled.
If you have extra time, consider visiting the Getty Center, Griffith Observatory, or the Huntington Library. If you have less time, skip day trips to Mount Baldy or Malibu Beach and spend more time exploring Los Angeles itself.
