I was able to get a reservation for 4 for breakfast. Is there a way to add more people?
You can call and see if they can add more people for you. Or you can try online again to check for availability with your increased party number. It won’t cancel anything until your new reservation is confirmed.
Most of the WDW restaurant tables for four really don’t have extra space- so you’ll need a bigger table to open up. Watching for the size you’d like and/or calling to see about availability are both good options. Stay flexible- and good luck!
