Public transportation is affordable and readily available throughout the city, as are Taxis and Ride-Share services. City buses cost $1.75 per ride, while ride-share services like Uber and Lyft can range anywhere from $10 to $50 depending on distance and time. If you prefer to drive, renting a car is also an option, but it is recommended to have a good understanding of LA's busy and complicated transit system.
If you're cutting your stay in half, it's wiser to bypass day 1. Meanwhile, if you have enough time, add Griffith Observatory to Day 2 and The Grove in Day 3. Finally, it's recommended to visit The Getty Center and LACMA on weekdays, respectively, to avoid excessive crowds.
