Not to total defend the CM's actions, there is never an excuse for a CM to be rude. But you should not call Central Reservations for NON RESERVATION Information.
Walt Disney World has 3 Information Lines:
CRO = 407-W-Disney (407 934-7639) for reservations
Dining = 407-WDW-Dine (407-939-3463), for Dining Info and PS's
General Information: 407-824-4321, All other Info.
For the information you needed you should NOT have called CRO's, you need to call General Information. Just like you should not call CRO for Dining Reservations, you should call dining.
If you call the right number, it is amazing what kind of information they will give you.
