We have actually had many discussions of this. He can only "cancel leave" if there is someone else who would like to take his vacation (if that makes sense?? ) Working for the Fed. Gov (he's an Air Traffic Controller) really limits how/when they can take vacation. They bid in rounds by seniority so he is already near the bottom and they go 7 days at a time. So the earlier they announce the easier it will be for him to talk with people to ensure he gets those dates. I have no idea if that all makes sense. I just wish they would announce it already so that we can start making plans! Grrr Disney... I'm a planner and organizer and not being able to do this STRESS ME OUT!
