You can basically avoid lines altogether at Disneyland or Walt Disney World. Not only can you book Fastpasses to walk right onto Space Mountain, but you can also skip waiting in line for food by using mobile ordering. Using the My Disney Experience app on your smartphone, you can order from quick-service locations at all six American Disney theme parks. In Disneyland, you’re given a window for when you want to pick up your food. In Walt Disney World, you press that you’re ready to pick up your food when you’re in the area and it will be hot, fresh and ready for you.
