You start on the Costco Travel website and it takes you to a custom page on the Disneyland website. That's where you do the booking and pay an initial $200 deposit. When done, you link the reservation number into your Disneyland account and it will show up as a regular reservation (with a small Costco logo in the corner of the page).
And if you call Costco Travel's phone number for Disneyland vacations, you will actually be talking to a Disney CM. (A CM told me she goes back and forth between the Costco Travel desk and Disney Travel's desk as needed.)

I would suggest to put the minimum down payment. Then, get Disney gift cards from Target with red card to save 5%. Apply the gift cards from the Costco travel site.
