* Disneyland Park is located in Anaheim, California. It's the original Disneyland park and opened in 1955.
* Walt Disney World Resort is located in Lake Buena Vista, Florida. It is a larger resort with four theme parks, including Magic Kingdom, which is often called "Disneyland" by people in the East Coast due to its similarities.
So, both are Disney theme parks, but they are different locations and offer slightly different experiences. Which one is "proper" depends on your personal preferences and where you are located.
