Don't want to get into an argument but...
If CRO is responsible for making reservations, it doesn't seem silly to me to call them about reservations policies regarding AP. Sure those folks can make a mistake like anyone else, but so can the CM standing in the resort. I would be terrified to think that confirmations (prices, etc.) hold no weight upon check-in even if the resort CM feels the CRO person made an error. After all, isn't CRO operated by Disney?
We own our own business, and when an employee makes a mistake that appears to be a negative to the customer, we (my husband and myself) "eat" that expense ourselves and try to turn the situation into a positive learning experience so it won't happen again. Again, I'm don't wish to argue, I'm just confused myself now.
