We went with 9 (5 adult, 4 kids). They put two square tables together, with the people against the wall sitting on the benches, the people sitting opposite were on chairs. It was fine, I wouldn't let a large party discourage you from eating there, The Plaza is great! You will have trouble, however, if you do not made a reservation, an ADR with a large party is a must, imo, especially inside the parks.
