Hi there Kathryn, welcome to planDisney! We're so glad you're here!
How exciting that you'll be visiting the "Happiest Place on Earth" during Halloween time! It's one of my favorite times of the year to visit, the pumpkins and décor all throughout the resort is spectacular!
I'm sorry to hear you're having trouble with your
theme park reservations, let's take a closer look to get this straightened out. Make sure you're logged into your Disneyland account on the
Disneyland Resort site, and then navigate to
theme park tickets and reservations. Click on "Make or Modify Park Reservations" and you'll be directed to the
theme park reservations page. I would then click on "
Retrieve Hotel Reservation" where you'll be able to type in the confirmation number you received from your Costco package confirmation email, and your arrival date. From there, you should be able to secure your theme park reservations.
I'm crossing my fingers that you should be good to go once you follow those steps, but if not, do not worry! I would reach out to a helpful Cast Member via the
Tickets guest services line, and hopefully they can get your reservations sorted out.
If you have any other questions Kathryn, please do not hesitate to
come back to planDisney and ask!
Have a magical day!
Melissa
