This feature would work best if it was guarded by some more restrictive restraints:
1) it would only come in full weeks, possibly multiple of them, but no days, and during this time you would not be allowed to log in at all;
2) it would freeze everything for the given number of weeks: cougars' timers, film making, web, Fred's sales, trainings, protections, basically everything;
3) you wouldn't earn a dime during this time;
4) you would be dropped out of any league, meaning you won't be attacked or challenged, and after the vacation runs out, you return to all those leagies with exactly the same score you had when going out. And due to break being a whole week, you'd reenter the leagues at the same stage as you were when leaving, so you couldn't cheat the league system;
5) it would cost a bunch of CC. Seriously. It doesn't make sense otherwise.
