Call the dining phone number and make reservations for any group of 10 or more. They will be able to help you! When we travel with my extended family, we are a group of between 20-30. We have had good luck calling and getting reservations, but it could be because it was a Magical Gathering family reunion and not just a large group traveling together. The thing to keep in mind is that at 95% of locations, your party will be broken up into multiple tables. Most of the dining rooms on property just don't have the space or capacity to safely seat large parties all in a row at one table. There are several that do, and dining should be able to help you select these locations. But we have been able to get seated at places like Chef Mickey's and Crystal Palace all in one row at the long booths that are multiple tables. I know off the top of my head, you will have issues sitting all together at California Grill. Via Napoli has some longer stretch of tables that may be able to pushed together, but I would not count on it. You will still have an AMAZING time even if you have to split up. Good luck getting into the places you are hoping for!
