A large part of the reason I took the job I'm currently working at is the slightly shorter work hours combined with flexible work hours means that I can put in a bit less than two hours extra for four days and take the fifth one off. Do that on both sides of the weekend and your mini 3 day holiday becomes one where you get waaay more time at your destination and more than the travel time even if you're spending a large part of a day at each end travelling.
