To me, if you don't know mostly what you're building by Thursday of week 1, you're already late.

As for meeting schedule, we'll spend nearly all the days and later hours in the first week (and perhaps last week) but in general it looks like this:

Saturday 9am-5pm
Sunday 1pm-5pm
Monday 3pm-6pm
Thursday 3pm-6pm
Friday 3pm-9pm

There is typically additional time spent by folks off-hours or off-site machining parts.

I would avoid the two-sessions thing.
