I scrutinized the school calendar to try and minimize the damage for our next year trip with our two boys who will be 13 and 17 and in grade 8 and 11 when we go. I ultimately decided Sept 1-12, 2009... and they will only miss the first 3 school days as labour day is later next year. So for a 12 day vacation, the days missed hopefully won't have too much of a lasting impact. The first time we went, my husband was home on leave from Afghanistan, and we went Jan 15 -24, 2008... The kids missed 9 school days (and my oldest missed grade 9 provincial assesment tests... he had to do them after coming home)... It was really hard for them to catch up, and it impacted their grades all year. I really don't want to have to make them go through that again, but it also was a special-circumstance family trip as they had not seen their Dad for 6 months. It was a special, magical trip... one the kids talk about all the time and we are all looking forward to going back to that magical place where we were all happy and the family memories were so special.
