If you're planning a Disney vacation, you've no doubt heard the term "FastPass." So what is a FastPass? FastPass is a way to reserve a time for an attraction or ride and bypass the regular line. You can reserve three per day, at a single park, through the My Disney Experience app or online. Anyone can make a FastPass reservation and it is a free service, as long as you have a park ticket. When your FastPass time window opens, just show up and enter the attraction through the FastPass entrance, making your wait time much shorter than the stated wait time.
