I just wanted to clarify something. There are two different things that conceivably could show up on one's credit report. This thread touches on both, and some people might be confusing the two.
1. When you first apply for credit, Disney runs a credit check on you. Whenever anyone checks your credit report, that inquiry is noted on your credit report. (The exception is when you look at your own credit report; that's referred to as a "soft inquiry," and no record of it is kept.) If you have too many people looking at your credit report, that can be a sign to potential creditors that you might be in a financial bind. I don't think there's any way for a potential creditor to check your credit without it being noted on your credit report. If such an inquiry is not noted, it's probably only because the credit bureau goofed (which happens).
2. Let's say Disney approves your financing, and you start paying. Every month when you make a payment, Disney has the option of reporting to the credit bureaus that you owe $x and that you have been making payments on time. The advantage to Disney doing this is that it could enhance your credit rating by showing potential creditors that you have a history of paying on time. The disadvantage to Disney doing this is that it shows potential creditors that you already owe another party (in this case, Disney) $x, which could affect that amount of credit a potential creditor would be willing to extend to you. For better or worse, the concensus is that Disney does not report on-time payments to the credit bureaus. Apparently, Disney will only report information about you to the credit bureaus if you're seriously late or go into default. As a result, as long as you pay on time, future potential creditors would have no way of knowing that you owe any money to Disney. If Disney's original inquiry was made less than two years ago, the potential creditors would see the inquiry on your report, but they'd have no way of knowing that Disney actually approved the credit and that you executed a deal (again, unless you stopped paying on time).
I hope that helps.
