We decided to bring my son's friend along with us. So, we now need to modify all of our ADR's from 3 people to 4. What is the best way to do this? Even though I have added the friend to MDE, I can't find a way to modify the dining reservations, only an option to cancel. Will I just have to call?
You will have to call dining reservations to see if they can modify your reservations. In many cases going from 3 to 4 might not be too difficult because in many restaurants you will be seated at a 4 top anyway. However, there might be some reservations the CM will not be able to modify. For those you will need to start checking online multiple times a day to see if someone cancels. If you are flexible about the time and/or date you may have a better chance. You can also subscribe to the Cancellation thread for the month you'll be going. It is on the Dining Reservations sub-forum.
