How can guests participate in the Disney Parks app's virtual queue system?

Guests can participate in the Disney Parks app's virtual queue system by joining a virtual queue for select attractions. This system allows visitors to reserve their place in line for popular rides and experiences within the park without having to physically wait in the standby line. Once they join the virtual queue, they can enjoy other activities in the park until it's their turn to experience the attraction. This method enhances the guest experience by minimizing wait times and allowing for a more enjoyable visit. Other options like booking a dining reservation, purchasing a fast pass, or signing up for merchandise notifications are unrelated to how the virtual queue system specifically operates.
