Hello there Lisa, so glad to see you back here at planDisney!
How exciting that you have a trip planned during
Halloween Time at the Disneyland Resort! It truly is one of my favorite times of year, you cannot beat all of the festive décor and beautiful pumpkins!
To start, make sure you are 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 can then type in the confirmation number you received from your Costco package confirmation email, and your arrival date. From that point, you should be able to make your theme park reservations for your trip! You can always reference the
theme park reservation availability calendar as well if you want to check availability of certain dates. If you are still having issues, you can reach out to a Cast Member via the
Tickets guest services line, and hopefully they can help get your reservations straightened out!
Since you will be visiting during Halloween Time, I do want to let you know that
Oogie Boogie Bash will be taking place on select dates at
Disney California Adventure Park, and the park will close early on those dates. For those dates, I recommend either making a theme park reservation for
Disneyland Park since it will not close early for any special events, or upgrading your ticket to a
Park Hopper ticket if you haven't already. That way you'll be able to easily make your way over to Disneyland Park if Disney California Adventure Park is closing early that day for Oogie Boogie Bash.
I hope this information was helpful for you Lisa, and you can secure your park reservations soon. If we can help with any other questions before your trip, please
come back and ask!
Have a magical day!
Melissa
