"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. Both the sixth expansion pack for The Sims 2, called The Sims 2: Bon Voyage, and the first expansion pack for The Sims 3, called The Sims 3: World Adventures, feature a similar theme. Vacation introduced a new neighborhood, called Vacation Island, where Sims could take vacations with family members or with other Sims. Vacation Island is split into three distinct environments: beach, forest, and snow-capped mountain. Sims can stay at a hotel or rent a tent to go camping. They can also get souvenirs to remember their vacation."
