I'd say yes. Otherwise you could just vacation pause for months(didn't see a time limit for vacation pauses) and leave the realm hanging with an inactive lord while there would be active players being left out. Losing positions is good for the game.
There is a limit, though I don't remember what it is offhand. I think it's in the vicinity of a month (which, of course, is probably still way too long to allow Lordships to be in stasis).
