I'm curious to read about what it means to "de-stress" from work but I think you forgot the [1] citation.
Maybe this is not common, but if I worked at a company with "unlimited vacation", I would definitely take extended vacations occasionally. I think as long as you timed them appropriately and gave advance notice, you could easily take a week or more off.
I work for a Boulder tech startup with an unlimited vacation policy.
Last year I took a month in Japan and South Korea, I just returned from two weeks in Tokyo, Taipei and Hong Kong. I also spent two weeks in Europe earlier this year, plus some odd long weekends and a planned week away around Christmas. I think my total for 2014 comes to around six weeks.
We also have a policy of working one month a year remotely from anywhere and the company pays part of the expense. I'm heading to Hanoi next year to take advantage of that. Our CEO/co-founder took his family to Australia for a month.
It is compared to a "long weekend" as described in the parent comment. Although it would be nice, taking a month off every year would be grail-status vacation time for a US employee I think.
Twenty years ago, back in England, I had 5 weeks of vacation and standard public holidays. I moved to the United States and after twenty years I have "progressed" to zero vacation days and all public holidays as unpaid time off.
