This feature (available for paying members only) adds even more protection to your games to avoid sudden timeouts. If it is turned on (on Settings / Calendar page) and in the event a player's game would otherwise timeout, the automatic vacation setting will use a vacation day (if available) to prevent the loss of that game. Of course, this action happens only if the player has at least one vacation day left and the game's time control allows to use vacation days.
