Yes - just go to the WDW website & sign in. Then mouse over the orange suitcase "My Disney Vacation" in the upper right corner. Under the options it lists, click on "dining reservations." It will provide you with a box to put in the confirmation number & phone number of for the adr you made & then click "retrieve reservation." It will bring up your adr info (you may have to scroll down a bit to see it). You won't be able to make any changes to your existing adr, the only thing you can do is cancel it. If you want to cancel it, there is a button in your reservation info to do so.
