I think schools should have mandatory classes during Chol Hamoed, for the sake of the parents sanity. I have a new bumper sticker, I hate Chol Hamoed trips.
letakein, so 2 and half months in the summer is not long enough? Plus Mid Winter, Legal Holidays and yomim Tovim, the hardworking kids need more vacation? How about the parents getting some vacation?
In my school a modern orthodox religious zionist school in cleveland we have school for 2-3 days of chol hamoed sukkot and no school on chol hamoed pesach. While we have school the middle school and high school do not have class and instead go on a chol hamoed trip as a high school on one day, and on the other day we learn about inyanei dyoma and eat a school sponsored lunch at a teachers sukkah.
