Here are some travel tips that I always pass on to my clients.

Make 2 copies of your passport - take one with you and leave the other copy home with a family member.
I suggest everyone get a visa debit card - if you do not have please apply for one as soon as possible. Alert your bank that you will be using your visa debit card in Italy. Otherwise your account may be frozen and you will not be able to access euros.
Use the visa debit card to obtain euors while in Italy.
When making purchases use your credit card
Make two copies (both front and back) of your credit card and visa card. Bring one copy with you and leave the other copy home with a family member.
Expect cool mornings and evenings so be prepared to layer your clothing.
Always bring an umbrella. I cannot guarantee sunny weather.
Wear or bring comfortable shoes since we will be doing a lot of walking.
You may wish to buy ear plugs to use during the flight to Italy.
You may wish to go to your bank to obtain a few euros before you leave.
Travel insurance is highly recommended. Purchase Travel Guard here.
Verify your medical insurance coverage before you leave the states.
Leave copies of your itinerary and copies of your passport with responsible individuals at home.
Access the State Department website for current information concerning your proposed travel locations.
