Walt Disney World Annual Passholders receive a discount on tickets for Mickey’s Not-So-Scary Halloween Party, but not all dates are included. Most October dates do not have a discount. If you’re searching for tickets on the Walt Disney World website and the date isn’t available, check near the top of the page, right below the picture of Mickey and Minnie. If you choose “Products and Prices for All Guests” all the available dates will appear. The price shown is the full price without the discount, so change it back to “Products and Prices for Annual Passholders” if you want a date that has a discount.
And yes, Halloween is already sold out.
