If you buy a regular Disney ticket first, you can upgrade to the fast track before entering the park. Usually, you can upgrade your fast-pass ticket on Disney’s official website or at the service center in the scenic area.
The specific price will vary according to different packages and time. It is recommended that you directly visit Disney’s official website or contact official customer service to obtain the latest price information. Fast Track ticket prices may change for different time periods, so inquire directly to get the most accurate quote.
