If you don’t plan to spend a lot of extra money on your next trip or want to stick to a budget, consider getting a reloadable credit card. These cards will help avoid stolen card numbers and even provide a money lesson for your children. FamZoo, a virtual family bank, offers a prepaid Master Card that allows you to control your accounts and the money rules within them.  This includes scheduling tasks for your children to complete in exchange for money (or even to lose money). Some of the other convenient features are instant or scheduled transfers between cards, activity alerts (great for knowing what your children are buying and where), the ability to lock and unlock cards, no foreign transaction or ATM fees, and purchase reimbursement. There are small monthly fees, but discounts for paying in advance.
