It depends...if they are on a boat taking a long sea voyage, then I'm going to "red line" it. But if they are stranded in the wilderness, lost with no idea of where they are, then we are going to do every day, set watches at night, roll survival for direction and food, etc.
I've only done the second version once in the current game and it is a nice change of pace. But if they wander into the Mournlands (Eberron game) then we will be doing much more of that.
