Do: Invest in Parkhopper Tickets
The Disneyland parks are located next door to one another. If you’re headed to California Adventure, go ahead and invest in the Parkhopper option so you can jump over to Disneyland throughout the day.
Don’t: Forget Your Comfy Shoes
Despite the fact that they are next to each other, going from one park to the next requires a lot of walking. Make sure you wear comfy, broken-in shoes to make this as painless as possible.
