Apparently, guests at Walt Disney World are currently unable to book FastPass+ reservations.
The service interruption is affecting all booking online and through the app, but in-park kiosks are still able to book FastPass+ for guests. All existing FP+ reservations are unaffected in the outage.
If guests try to book online, the system informs guests that distribution has concluded for the day, which is of course, inaccurate.
Disney is unsure of when the problem might be fixed, stay tuned for any updates as they are provided.
Its working for us
Just booked 1 fast pass, and re tried it. Its letting us get passed the date section and not loading available times
Its back up now! :)
