We normally have a party of 12 but we have grown to a party of 14 this year. I am usually the planner. What I have found is that if you are trying to make the reservation online and it says to call, that means the restaurant cannot seat that many people at a table. I usually make two or three different reservations and tell the hostess at the restaurant as soon as I get to the park. 90% of the time they can accommodate and get us next to each other. The key is to be nice about it. The CMs understand these are usually family meals and everyone wants to be together at Disney! Good luck!
