I did!
When I first read about this, I too hated it. But now, I've gotten POR for 850.78 for 7 nights, with no phone calls, no changing my dates, no changing resorts. When I last talked to a CM, I asked if I could pay before I went down, she told me to hang on, not to pay yet, that she thinks they might go down a little more. She said they were trying to stop the "credit your credit card, to turn around a charge your credit card." Apparently people have been complaining about this, and saying that Disney is messing up their card. If we don't pay until we check in, then no one has to worry about screwing up their credit card.
But then again, I've heard several reasons for this new system. I am not with the majority, I like this new system. And, sorry, but I even told the CM on the phone that I liked it, and I told her I hope they keep it. I'm not able to take quick vacations any time of year. I have to know when I'm going on vacation at the beginning of the year (for my job) and schedule it then. Then, all I have to do is decide what I'm doing on that vacation. Well, I only like to vacation down there, so the decision isn't to hard. Trust me, I wish I could just book a quick trip here and there, but cannot. So, this plan is great for me!
