I called them to ask (we wanted to make sure we visited when they were having fireworks) and I was told that yes, indeed, there will be fireworks during the weekdays that week.
One of the reasons we go during the Christmas season is that there's Fireworks every night (spoiled by WDW). Christmas season starts after Veteran's Day and lasts through the end of the year. If you came the first week of November, you would be free and clear Mon-Thurs, plus the parks would be ghost towns.
