It's almost summer vacation season here in the nation. Most take time away from work between late July and early August. A new survey suggests more than half of Koreans, 60 percent, are planning to take a vacation during that time. The poll released Thursday was conducted by Hunet, a human resources consultancy. Plenty of people are skipping it though -- 16 percent, in fact. They cited financial difficulties, too much work... or plans to go on holiday some other time. The survey found respondents are planning a holiday that'll be, on average, 4-point-3 days long. The cost: around five-hundred-thirty U.S. dollars... some 15 percent increase from last year.
