We are a party of 4 and made most of our reservations for our trip. We just found out relatives are going the same time as we are and am trying to include them in some of our dining reservations. They are a party of 5. I am having a hard time finding reservations for a party of 9. I am trying to do everything through the MDE app and also trying on the WDW web site. No luck. If I call Disney reservation on the phone would I have better luck or do they see the same availability as the app and web site?
