The Sims: Vacation, known as The Sims: On Holiday in the Republic of Ireland, the UK, China and Scandinavia, is the fourth expansion pack for The Sims. Vacation introduces new items, characters, and features, as well as a new destination called Vacation Island where Sims can take vacations with family members or with other Sims. This marks the first time Sims can stay on lots away from home, meaning the game can be saved while a Sim is on Vacation Island. Vacation Island is split into three distinct environments: beach, forest, and snow-capped mountain. Sims can purchase or find souvenirs and either stay at a hotel or rent a tent/igloo.
