Additional Travel Expenses will pop up, so please plan for it! Not all shops & restaurants take credit cards, so please make sure to have some cash with you. There are banks & ATMs that you can get money from, with additional fees.
All that the Italian Wellness Holiday has to offer might be enough for you, but if you plan on shopping outings, healing treatments, day trips, surfing, or wine... some spending money might be a good idea!
Travel and medical insurance is also recommended.
