You have to log out for a undisclosed amount of time in each inn (meaning u cant just go to bed in the inn, log out than log back in, you have to be loged out for a certain amount of time.) When I did it I made sure to log out in the inn before I was going to actually log out of the game and didnt log back in for 24 hours. The time that is needed to be logged out is unknown but I would say stay logged out for atleast 24 hours or so.
