I like the idea of auto vacations since they can be great when emergencies arrise. Brothers in the hostpital, wife goes into labor, house burns down and takes computer with it, etc.... When things like this comes up, it is nice to not have to think "oh no, I beter got to an internet game site and set vacations".

Of course some users will abuse it, but people also abused the last way also - so I like this new feature.
