If Disney went straight to the CC guarantee right out of the gate I would go with the letter. But they did not. They have tried several other, much less intrusive ways, to curb the problem and one would assume that they have not worked or caused other problems. (I know that caused other problems is quite true)That's the only explanation. And like I said, if it blows up in their faces, I'm sure they will course correct.
I try to always see business decisions from the standpoint of the business. I get the refillable mug situation, for example. But I'm having a hard time seeing past the guest point of view in this case. I (obviously) have a very strong, negative reaction to this decision on a gut level.
I may even write a letter. And I never do that.
