There are various methods you can use to get to Disneyland. The most obvious is to drive there in a car, but that's not the only route. The easiest method is to stay in a nearby hotel and use the ART. The advantage is that you will avoid a long trip to get to the park, so you can spend more time inside. Even many locals choose to stay in a hotel.
Anaheim Resort Transit System (ART).
[April 2021 - Service is limited while the parks are closed]
This shuttle provides transportation from most hotels near Disneyland to area attractions including Disneyland, Downtown Disney, California Adventure the Convention Center, Anaheim Gardenwalk, the Crystal Cathedral. If you need/want to go shopping, The Outlets at Orange (shopping mall) and Segerstrom Center (performing arts in Costa Mesa) are on the ART routes. The ART shuttle also provides transportation to top restaurants in the area, such as Ruth Cris Steak House, Bubba Gump Shrimp Factory and Lucilles BBQ Smoke House. You can even take the ART shuttle from the Disneyland area to Knott's Berry Farm and nearby attractions in Buena Park. Note: You can buy ART passes online, or at hotels and kiosks in the area. You can pay a cash fare on board, one-way, exact amount only (change is not given). However a day pass costs just a little more than a one-way fare so it pays to plan in advance.
