The only number you can call to reach CRO is 407-WDISNEY (407-934-7639). It will ask you to enter the number of nights you'll be staying. People (including myself) have been getting CRO by entering that they'll be staying 2 nights.
If you still end up with the travel company, ask to book a room only reservation with no extras, 1 night's deposit, balance paid at check-in, and a 6 day cancellation policy. The WDTC (I think) are being trained to book room-only reservation with the favorable CRO policies.
