Seeing advice on a $0.01 per night booking:

1. I booked a marriott property (Autograph collection) online with my corporate rate. Total was $150 per room per night.
2. I had to change length of stay from 3 nights to 2 nights for both rooms, so I called and had the property make the change.
3. Now, when I look at the confirmation online (clicking "View/Modify" under "Trips"), the rate for each night is 0.01 (taxes included) for a total stay of 0.02 for each room (local currency, USD).
4. I subsequently called Marriott reservations to inquire about the rate to confirm my reservation and ask if that rate is valid and they confirmed the reservation at that rate.

As much as I want to get that good rate, I want to be realistic and avoid any potential headaches during check-in.

Will this rate be honored? Any advice?
