I’m sorry, I don’t have first hand experience with booking a large party. However, I’ve read here on the boards that people have more success splitting the party and making 2 ADRs for approximately the same time, then ask to be seated together at check in. Obviously there’s no guarantee, but it’s worth a shot.
