Where my oldest goes to college they don't have class on Fridays. Last year Veterans day was on a Tues. and with the Disney Visa we got
free dining, so we left Thursday after class and were there Fri, Sat, Sun, Mon, Tues, and were home Tues night. So she missed a Monday and we had a 5 day trip. We also were very lucky to have her spring break the same week as the public school so went in March for a week.
We probably won't go again for a while though, I have 3 different school's schedules to try to coordinate now...kids in kindergarten, middle school and high school, one at a jr. college and DH in grad school at the univ.
