Hi there Shannon,
Welcome back to planDisney and thank you so much for your question! It's so great to hear that you're making the trek to the West Coast to visit the Happiest Place on Earth - during the spookiest time of year, no less!
First, I'm excited to hear that you're going to get brunch at
Goofy's Kitchen - I'm guessing it will be the new Halloween Brunch offering? That should be so much fun!
After you're done with brunch, your best bet to enter Disney California Adventure Park for
Oogie Boogie Bash - A Disney Halloween Party is either the front entrance or the secret entrance (more on that below). Since the
Disneyland Monorail does not stop in Disney California Adventure Park, you would not want to take that if you're planning on heading in right at 3:00 PM.
The Disneyland Monorail has a stop in Tomorrowland in Disneyland Park, so I love using that - especially in the early mornings - to try and pass by some crowds at the main entrance. They will scan your theme park tickets at the
Downtown Disney District Monorail stop, so you'd want to have yours ready before riding.
However, since
Oogie Boogie Bash - A Disney Halloween Party is held in Disney California Adventure Park, my recommendation when you're done for brunch is to head to
Disney's Grand Californian Hotel & Spa to enter through the "secret" entrance! You can enter through here for for standard theme park hours and special events and - in my experience - it tends to be a bit quicker than the main entrance.
I hope you have such a fun time visiting the Disneyland Resort, Shannon! Thanks again for your question. Please feel free to come back and see us here at planDisney if you think of any follow-ups.
Have a Magical Day,
Greg
