Let me point out that unlike the way that the previous simcarnations have done it, World Adventures is not about having your sims going on vacations in the traditional sense. Your sims will not be building castles but may be exploring the catacombs under one of them, they will not be getting sunburnt but may be burnt by fire traps if they do not watch their step. The only thing similar is that your sims have to save up to get there. Once they have saved up enough money to visit an adventure destination, which can range in price, they are there for a minimum of 3 days. They can only extend this by adventuring while they are there to get Visa points for that location.
