Why doesn't she want to use one of her vacation weeks?
We're still under temp agreements that don't include vacation specifications and haven't established the advance notice requirements yet. We're still in the middle of mediation/arbitration but life happens.
My temp orders - issued nearly 8 weeks after I filed - lasted 1 year, 9 months, 3 weeks. Vacations were listed in the county guidelines which were referenced by the order. My ex insisted she could deny any vacation notices. She tried to get an Amber Alert, even spoke to someone in the news media after the sheriff's staff said it didn't meet the Amber Alert criteria. It never got settled in court, but my lawyer later said it was unclear.

Um, am I not to take my child(ren) on vacation for nearly TWO years? Yes, I know temporary orders are supposed to be just temporary, but I had alternate weekends, maybe 15% parenting time, for nearly TWO YEARS. We separated when our son was 3, the divorce was final when he was 6! Sorry, that's not temporary, that's prolonged virtual torture for us parents in a high conflict divorce.
