Take a long vacation or several short vacations in a year?
in my opinion, I definitely prefer to take a long vacation instead of several short ones. If the vacation is as long as about two month, I can separate it into two parts. In the first part, I will go abroad, visiting the place I have dreamed all the time,for example yellow stone park. When I get back, I still have one or two weeks to have a rest before go back to work. So I would not be very tired and be able to keep energetic while working.
