We're scheduled to play five two-hour levels today with a dinner break after the third. That's still the tentative plan for now, though we may end up trimming one level off the end of the night if play keeps progressing this quickly. The staff has also told us that the field will break for dinner early if they get down to 36 players before the end of the next level.
The survivors will play at least one more level after dinner, and they'll continue on for one more level after that if we still need to thin the field further.
In short: Four or five levels with a dinner break today.
