This question is meta, linking ingame-time to real-time: How often to make camp in Dungeon World? The desired answer is something like "plan to let them make camp every x hours of playing."
The obviously answer is: "go with the fiction", and it's a given that they won't make camp while under attack or while fighting a dragon. But when I as the GM plan an evening-long session (say 4 hours), should I plan it over 2 days in-game (i.e., one night of camping), should I plan a camp after every hard fight, or is a 4-hour session perfectly fine without camp breaks?
Despite "go with the fiction" and "it depends", I hope for GMing input of what's likely to give the players the most thrill — using up the right amount of rations, giving the wizard enough time to try his favourite spells, etc.
