It was very difficult planning family vacations every year with our cadet who is now a Firstie. The first summer he had 3 different things he did, so he came home for a week or less between each of his requirements. We also did not have any of this finalized until March. Some summers things got changed just a couple of weeks prior to when he was to report. So tell them if they want to plan something that includes you, then they will need to wait for planning and be prepared to have you not go at all.
