Assuming I can't use my PBDs before the end of the year, but I can before the end of March, it sounds like the days would first have to be dropped as a Personals drop which has huge limits on my category due to the way they staff reserves. They'd then need to be converted to PBDs, is this correct? Lately it seems like the chances of a personal drop are slim to none, and the APD has been used already.

If used as supp vacation do they need to go through the standard vacation bid?
