However, ride-share services such as Uber and Lyft and taxi services are available and reliable. Expect the travel time between destinations to be between 15-45 minutes depending on traffic.
If you have more time, consider visiting nearby attractions such as the Los Angeles County Museum of Art, The Hollywood Walk of Fame, or the famous beaches of Santa Monica. If you have less time, consider combining some of the suggested places or cutting some items from the itinerary.
