We recommend getting your passport as soon as possible as the wait time can be rather lengthy. However, it should be done no later than 6 months before traveling to Italy.
Typically, the flights are at the best price 3 months before traveling.
Dressy Casual is the dress code. For men this means slacks and a dress shirt with or without a sports coat. Please, no jeans. For women, this could mean a midi or maxi dress.
