I have always taken my son out of school for our Disney trips (please don't flame me - he is a good student and I think he learns a lot on our vacations). Now he is in high school and I like to plan our trips at the 11 month booking window for DVC and for early December or January. The school won't tell me when exams are so I'm afraid to book. Do all the schools in Ontario have exams at the same time? Does anyone know when they would be? We live in Windsor if this helps. Does anyone who have kids in highschool take them out for vacations and does anyone have any tips? Thanks.
