If your partner and/or your children arrive after one year has passed since you arrived, they will no longer be eligible for the discounted price, meaning they will be treated as separate and will have to pay the same price as the main person. E.g. your husband and 2 children have arrived 2 years after you arrived. They will have to pay the following fees: husband (person 1 fees), child 1 (person 2 fees), and child 2 (person 3 fees).
