These days count against Sim's vacation days if they are employed, so job performance will lower if employed Sims vacation too long with no vacation days available, but only on days when they have work. A vacation can last for up to seven Sim days, but can be extended.

Sims can only visit this world by vacationing there. The world consists of two neighborhoods which feature a national park, and five lots for rent (four houses and a campground) in the other. Outdoor Retreat introduces a new world, Granite Falls, which is only accessible while on vacation. Outdoor Retreat focuses on outdoor camping, similar to a vacation in Three Lakes in The Sims 2: Bon Voyage. It includes a new destination, many new objects, new outfits and new interactions. The Sims 4: Outdoor Retreat is the first game pack for The Sims 4, released on January 13, 2015. The most recent game pack, Dream Home Decorator, was released on June 1, 2021.
