It is recommended to rent a car in order to travel around Southern California. The distances between the different attractions are relatively large, and public transportation is not always efficient or convenient.
The travel time between the different attractions should be accounted for, and it is recommended to use a GPS or a map application to avoid getting lost or stuck in traffic. Gas prices are relatively high in California, and travelers should budget accordingly.
If you have more time, consider adding an extra day to your itinerary in order to visit popular attractions such as Universal Studios Hollywood or the San Diego Zoo. If you have less time, consider skipping Disneyland Park and focusing on the other attractions that are closer together.
