Hi Lesley!
Thank you for bringing your question to the Disney Parks Moms Panel. I'm so delighted to see you will be visiting
The Happiest Place on Earth at my
favorite time of year, Halloween!
Not only will you have the opportunity to see
Haunted Mansion Holiday and Radiator Screams, but you'll have the added convenience of staying at a Disneyland Resort property,
Disney's Paradise Pier Hotel. The first thing that works in your favor is that you'll be visiting during the week! Disneyland Resort has a lot of local visitors each day, so anytime you can visit while the masses are in school or at work, this is definitely in your advantage. While Disney does not release a crowd calendar for you to estimate, there are plenty of third party resources that I've used in the past for planning a trip. I'd certainly recommend doing a quick internet search for "Disneyland crowd calendar" and from what I can see, you are definitely in the clear. Many will even show you a split between
Disneyland Resort and
Disney California Adventure Park so you can plan your days out if there is a significant difference. When you arrive on Sunday, you may find it to be a tad busy, but for the rest of the week I think you'll find everything will be very manageable, not too busy and weather wise, you couldn't ask for a better time to go!
I hope this helps in planning your upcoming visit! Please come back and let us know if we can help in any other way.
