Well hello there, Lynn!
Welcome to planDisney and thanks for coming to us with your question! I hope you're having the most magical of days! I'm sorry to hear that you're having some difficulty linking your Costco reservations. Let's see if we can't troubleshoot the issue.
I'll go over instructions assuming you're using a desktop computer. First of all, you'll need a
Disneyland account if you don't already have one. Once you've created an account or logged in to an existing account, head over to the
Disneyland Resort website. Hover over "My Disneyland" on the top bar to pull down the menu and select "My Plans." On the next page, you can select "Add More Plans" to link your Costco Travel Package. When you booked your package on the Costco Travel site, you should have received an email detailing your itinerary. Locate the confirmation number on this message and enter it along with the last name on the reservation. That should link your accommodations and tickets to your account.
Now for reservations, head to the
Tickets and Reservations page. Select "Make Park Reservations" and select your desired dates and Parks. Beforehand, you can check the
Availability Calendar to make sure your dates are still open.
You should be all set from there! If you are still having issues, you might need to contact Costco Travel to address the issue. Don't forget to make any
dining reservations you desire! You'll be visiting during the
Food & Wine Festival at Disney California Adventure, so you might be able to fill up with the delicious foods on offer there! I'd recommend getting the Sip and Savor Pass and studying the
Foodie Guide to see what piques your interest. Here's a tip: if you know the dishes you'd like, you can order them all from one booth and keep your receipt to show at other booths to just pick up your food!
I hope this answer was helpful, Lynn, and that you are able to link your package and make your reservations without issue. Please feel free to visit us again at planDisney if you have any other questions! We're here to help!
Have a Magical Day!
