I like my vacations better this way. Humans are built to adjust to their situation. It benefits us, from an evolutionary standpoint, to stop enjoying ourselves and start looking for potential enemies. So in that sense it doesn't matter to me if my vacation is interrupted.

So I can't do three week vacations. I take three one-week vacations interspersed with (on average) a day or so of work. I find I have more fun that way anyhow.

Sure, but the flip side is the incredible day-to-day flexibility you have to engage in whatever interests or random fun activities that pop up. I can easily take afternoons and days off, or sleep in until 11 if I want.

I've been running my own business (web dev) for more than 6 years and I take vacations whenever I want (except when we are delivering a project) I only make sure to travel places where I can find good internet access.

Remember those "offline" weekends? They are gone too... :)

Vacations are a thing in the past indeed... =)
