While the offerings of Star Wars: Galaxy's Edge are exactly the same at Walt Disney World and Disneyland, there is one huge difference. At Walt Disney World, there are only two entry points to Galaxy's Edge, one from Toy Story Land and one from Grand Avenue. At Disneyland, families can enter from three entry points: one in Fantasyland, one in Frontierland, and one in Critter Country.
Depending on what you want to do can help determine which entrance you and your family should us — especially if little legs are tired. For example, at Walt Disney World where we did our tour, the Toy Story Land entrance is closet to the marketplace and Millennium Falcon: Smugglers Run than the Grand Avenue entrance.
