That's what I did on my last vacation, and it was lovely.
Except that I was in a cabin, on an island, in a foreign country. And the reason I was absolutely undistracted from my book, is that I'd turned my phone off before crossing the border. And I left it off, all week.
The isolation and quiet surroundings made the "week off" truly off. Nobody could reach me if they tried. Whatever calamity befell my boss, he'd just have to wait.
That's so much better than I'd normally do at home on a week off, and it was 100% worth the travel to achieve it.
