Ah, okay - I do have the party make a Survival check to find a good resting spot, ask about watches and roll for chance encounters during the night that can interrupt a rest. I used to also call for Con checks from those on watch, but I've now set the DCs to about 5 as 10 was too ridiculously hard. I've dinged party members on recovering spells and/or HD if they don't have a bedroll or tried to sleep in armor.I meant the minutiae: safe location, watches, interruptions at night spoiling rest benefits, etc.
I've had more than one occasion that the party's camp has fallen afoul of something during the night, including ambushes, but its usually been just enough to keep the party mindful about sleeping out in the wilderness.
