The Main Hall fills first, especially for the first talk of each morning. If you want the front rows, arrive by 09:15.
Hall B is smaller and closer. Speakers there tend to take more questions, and the room runs cooler in the afternoon.
Lunch is the best time to meet people. The long tables are deliberately too long to sit alone at.
If you only stay for one evening, make it the first: the press in The Loft runs until nine.
