Though I was a Disneyland local for over six years, it wasn't my "home park" growing up. Originally hailing from the East Coast, I was much more familiar with Disney World throughout my childhood and into my early 20s before moving to California.
But as someone who visited Disneyland often, I loved spending more time in the areas you can't find in Orlando.
There are a lot of rides that are currently unique to Disneyland in the US, including thrilling rides like Matterhorn, Incredicoaster, and Indiana Jones Adventure, as well as all the Fantasyland rides like Storybook Land Canal Boats, Snow White's Enchanted Wish, and Mr. Toad's Wild Ride.
There's also Avengers Campus, a totally new land packed with Marvel characters.
I also love the rides you can find on both coasts (especially when I find the subtle differences between the two). But if I had family visiting from the East Coast, I'd make sure to prioritize the experiences you'll only get when visiting Disneyland.
