Hi Lacey,
There are still ways to enjoy the
Disneyland Fireworks show, even if you're no longer at the Park by the time the nighttime presentation begins.
For one, certain Disneyland Resort Hotels offer a concierge level experience where you can enjoy the fireworks. Many friends have told me you can also watch them from the pool area of Disney's Paradise Pier Hotel.
And if you happen to be around
Downtown Disney, I remember seeing fireworks not too long ago from the outdoor seating area of
Earl of Sandwich.
Unfortunately, guests who did not purchase a
Mickey's Halloween Party ticket will be asked to exit the Park by 6pm, which is when the Party begins.
I hope this helps.
Thanks for stopping by the Disney Parks Moms Panel!
Have a Supercalifragaslisticexpialidocious Day!
