I am not sure, there might be the option to buy rations (limited by str and money), but what I really remember about resting was the resting system in NWN2:MotB, if you rest you would lose soul points and if you failed you could lose a large amount of xp or die if you managed it poorly. I just thought it would be wrong if I didn't mention it, but there has to be some kind of limiting factor.
Another option is enemies, resting might also be limited by enemies, but not like in other dnd games(aside from MOTB), I suppose the best example of enemies hampering an ability to rest hasn't really been implemented well in dnd rpgs as they only might attack when you press rest like in bg1/sod/2, iwd1/2, etc. FE might be the best as resting for too long might lock you out of the best ending or the enemies will just keep attacking on the better designed maps.
Removal might not be in keeping with the tropes of the game, what are the limiting factors of the game, ie the economic limited resources in the story?
