Vacation mode serves to protect players against attacks and espionage during extended periods when they are unable to play. However, any attacks and espionage attacks that were launched against your castle before you activated Vacation mode will be carried out.
Once a player activates Vacation mode, he will not be able to log in to his account for a period of 48 hours. It is not possible to cancel Vacation mode once it has been initiated!
To avoid any misuse of Vacation mode to temporarily protect yourself prior to an attack, protection will only begin 12 hours after activation. Each player has 42 vacation days a year.
