Thought I'd revive this thread to post a buyer beware...
I've been trying for the last 30 minutes to pay off my trip (only 51 days left!). After waffling between Disney telling me that "payment details are at this time" and letting me through, only to stall in the payment process, then finally telling me it couldn't process a payment on my credit card, I was totally frustrated. Since it's after 9:00pm, I thought I'd just call in the morning. But then I found this thread with the link to the old website, so I thought I'd give it a try.
Only to find that my balance was $0.00.
I checked my credit card balance online to see if a payment actually had gone through and, sure enough, there it was.
As others have already mentioned, I cannot believe how horrible the Disney site is. For as much care they give to the presentation of their parks (and they really really do), it just seems crazy to me that they don't give as much attention to what, for many, is the first impression of what they offer. Looks pretty at first glance, but once you dive in, it's just a complete mess.
