Money is a very personal thing. How much you need is related to how you spend, what you buy and how often. If you are going buy Gucci products in Italy, you will need some money. We like to arrive with some Euros in our pocket. Maybe 200- 400 so we can buy tickets, take a taxi, etc. Most restaurants and stores take credit cards. There used to be a problem at some places because the European credit card machines require a computer chip on their credit cards. The US has finally caught up to the rest of the world and most banks are now issuing credit cards with both the old stripe and the new chip. Choose a credit card that does NOT charge an extra foreign transaction fee. There are many today to choose from.
You can get money from a European ATM easily. His is the easiest way to replenish your cash. Banks offer great exchange rates but can take a while to fill out paperwork and get your cash. When you are returning home, don’t exchange your Euros back to dollars if you plan another trip in the next few years. The double exchange is very costly. Hold on to your Euros with your passports and use them on the next trip.
Traveling is fun and money shouldn’t be the main concern. You are on vacation and you should relax and enjoy the trip.
