For longer vacations, it is almost impossible to plan a perfect daily budget; however, when you plan your spending money every 3-4 days, it is easier to plan. To make it easy on you, cash is the best way to avoid increasing your consumer debt. Take your budget and divide them into 3 to 4 day increments, (depending on your comfort level with the amount of cash you wish to carry) and then plan your withdrawals every 3 to 4 days. If there is still money at the end of the 3-4 day period keep going.
