Changing/Canceling ADR's while at WDW

[disneydownunder]

I am not bringing a mobile/cell phone on my trip from Australia, and I am staying at Pop Century. I was wondering is it a free call from your resort room to Dining Reservations to cancel or change ADR's?
If not, is there any CM around/within the resort that can cancel/change/book reservations for free while at the resort for on the fly changes?

Thank You

Yes, free from your room or you can go to concierge desk.

Great, thank you very much for your help. While I have planned all my ADR's carefully I am also expecting changing some plans at the last moment to suit our moods!

We've had much better luck changing/canceling reservations on line while on our trip. There have been several instances when concierge have told us no reservations available and I've gone online and found exactly the time and location we wanted--this happened with LeCellier, Aloha show, and Chefs during our late Dec/Jan trip.
