A few more points on IVD’s…

I’m pretty sure it needs to be from your secondary (or later) vacation.

Your category has to have 15% (or 20%?) of required reserve staffing on every day the trip touches, not just for the single IVD day.

Whatever day you put your IVD on you can’t pick up anything over that day.

You can’t drop a trip if your trip touches the day prior, day of, or day after a holiday!

Good Luck, May the odds be in your favor.
