If you were making a vacation plan for December 2007, here's a cropped example of what the report would look like for a 2-week OKW 1/B/R vacation.
Note the 7-month, day-by-day reservation dates that show when you can call. The program adjusts for weekends, and see how it adjusted for the Memorial Day on Monday May 28th, 2007, when MS will be closed, and you'd have to wait until Tuesday to call.
You can also have it show 11-month day-by-day dates, or set it for 'normal' view where it shows you trash and towel and full cleaning days.
