As Hopefully said, the Fantasmic packages are designed to fill tables during the less busy hours (e.g.mid afternoon) so even on the best of days during late November the last reservation would probably be before 5 PM. However, Nov 24 is Saturday of Thanksgiving weekend so most likely anything later has already been booked. Many have had success setting up a request on the Touring Plans reservation finder and you could also subscribe to the November cancellation thread at the top of this forum if you are hoping for a later time.
