The Sims: Vacation (called The Sims: On Holiday in the Republic of Ireland, the UK, China and Scandinavia) is the fourth expansion pack for The Sims. Vacation introduces 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. In other words, 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 stay at a hotel or rent a tent/igloo to rough it in the wild. They can also purchase or find souvenirs. As with other expansion packs, Vacation introduces new items, characters, and features pertaining to the theme of vacations.
