Haven't looked/experienced where you're at. But don't think the system will award you an intentional conflict with your vacation period.

On the plus side, you'll have a bunch of extra vacation hours to use.
Downside, have to decide if you want all the time off for two 14.5 CH paychecks...somewhat confident that you will be able to adjust your BLG higher once the makeup window opens this week. Just don't ask for that sweet 90 CH carryover trip or you'll be in the same hole
