It's best to rent a car for the duration of the trip, as many of the restaurants and attractions are spread out. Taxis and ride-sharing services like Uber and Lyft are also available. Keep in mind that parking can be expensive in downtown LA and at theme parks, so plan accordingly.
If you have more time, consider adding a trip to Santa Monica for seafood at The Lobster or a meal at the iconic In-N-Out Burger. For a sweet treat, visit Milk Jar Cookies or Bottega Louie. If you have less time, consider skipping the Disneyland day trip or shortening the food tours.
