The Rental Cabins are found in the northeast quadrant of Alan Wake 2's Cauldron Lake map, and they are home to a Cult Stash. Specifically, that container is in the southernmost cabin's bathroom, and there is a drawing attached to its top. That drawing points toward the key that is used to open the Rental Cabins Cult Stash in Alan Wake 2, and this guide is here to help players locate that item.
