Lived in Northern Italy for 2 years in a small village about 20 miles west from Venice. First the cautions; As previously stated, don't wear shorts out in public unless may be at the beach. If there are any ladies traveling in your group the no shorts in public is even more important. They will be construed as women of ill repute and will attract very UNWANTED attention where requests for services by men will be made in exchange for Euros or drugs therefore the attention of the local polizia or Carabinieri will also follow. Don't yell or shout. Doing these things are not only in bad form in Italy but lets others know you are a tourist and an easy mark for criminals, pan handlers and this time of year very aggressive gypsies better to fly under the radar when possible . Being with a native will benefit you. Don't flash money and if you go to market negotiating is required. Lake Garda is nice and if you speak German there will be a lot German tourist there for vacation this time of year. Verona is nice and has a Roman coliseum that is still being used for plays and concerts. Vicenza has a lot of goldsmiths in the city and you can do well buying gold jewelry there. Milan is very cosmopolitan and should be experienced. Godetevi il viaggio e di essere intelligente. (Enjoy the journey and be smart) if my Italian is any good after 30 years.
