If it were me, I would want DH to push for more info at work. Has he been approved for vacation for that week? Can they force him to come in on approved time off. My DH's work place has mandatory meetings all the time, but you don't HAVE to be there if it's your day off or anything. And no way would they want to pay the gas bill for him to drive back to Iowa from WDW to be at the meeting. Also, I would think if they knew what was going on, they may be able to schedule the meeting around is trip so it won't be an issue. Sometimes bosses tend to forget that someone is scheduled to be gone. I know DH's boss has had to re-schedule some special events when he found out DH wasn't going to be there to handle them (no one else seems capable!). If your guy is anything like mine he tends to take what info he is given and not ask for more. If he can push a little without getting into trouble (we don't want him losing his job over this!), then I would ask him to please, for your peace of mind, just go to his boss and remind him that you have a mini vacation for your DD's Bday scheduled for that week and could they try to plan this meeting around that, or at least give him a date so if you need to you can shift your plans around a little. Let us know how it turns out!!
