Yes they can, I have seen it happen first hand and it wasn't pretty
My guess is someone booked at an AP rate and didn't have one, am I close? I saw someone do that also.
This isn't the same...CMs are telling people there is no pin...how would a pin be required upon check in? I booked with a pin, and then threw my card away. Let them try to change my reservation. I'll let my 2 year old loose in the lobby. What about the people that never got a card but have a pin with their name? They certainly can't be required to bring it with them if they never knew it. Different than AP or
AAA. That is a membership card, this is not.
Disney isn't going to cancel 100s of rooms that they booked during a slow time because of this...The only people using this code without a pin are people that are on boards like this that heard about it. Very few in the whole scope of Disney. In fact, they might offer less rooms for
free dining, or compensate in some other way if they have to. As anyone that has had a flag waving Brazillian tour guide ahead of them, there are LOTS of people that go to WDW that know nothing about anything. Even though the Dis is large, it is kind of arrogant to think that even that many people have such a big effect on the behemoth we know as Disney.
Why on earth would Disney cancel or risk the cancellation of hundreds of rooms during a slow time? That would make NO sense. It would anger tons of people, many of whom booked a trip ONLY because of this and wouldn't have gone otherwise. That is what they want...more trips, upgrades, paying full price for dining, adding days...why on earth would they cancel anyone? This isn't like the other computer glitches people keep refering to, this has been going on for over a week! Disney is so so smart. I'd bet money they aren't going to risk losing all those bookings by trying to cancel them or charging people full price. They'll lose more than they'll gain.
