I called yesterday to confirm.
If you are financing, there are two things that may happen. If you have owned your membership for at least a year, regardless if it is a resale or direct, and wish to add-on direct points, you will not have a credit pull. The APR will be based on the down payment you place. If you have owned less than a year or are a new member, you will have a hard credit pull. The hard credit pull will occur for all individuals on the contract, so if you and your SO are jointly getting an account, the hard credit pull will occur for both of you. Once the credit pull has happened, they will let you know which APR you qualify for based on their calculations. They could not verify what they use for credit scores (TransUnion, Equifax, FICO 8).
The credit pull is good for 3 months in order for Disney to add points to your account directly. After the 3 months, if it has been less than a year for the age of your membership, they will complete another hard pull on your account. As a reminder, hard pulls are reflected on your credit score for 12 months. In turn, if you decide to finance and have them pull your credit, you will have 3 months to make a decision if your membership is under a year old.
If you are paying in cash, Disney does not pull your credit. Hope this helps!
