Hi and Welcome to the DIS!
Most have reported that Disney has been quite lenient in the credit approvals. After all, if one were to renege on payment, then they can simply freeze the account.
I have only heard of maybe one case in all the years that was declined. If credit is questionable then they may possibly ask for a higher downpayment, but they most likely will still approve.
Sounds like you will be fine with your own application! Good luck!
