For your trip, ensure your passport is valid for at least six months beyond your planned departure. Schengen Area countries (Switzerland, Luxembourg, France, and Italy) generally require a Schengen visa for non-EU visitors. Check vaccination requirements, especially for COVID-19, as entry restrictions may apply; it's advisable to get vaccinated and carry proof. Always review the latest travel advisories from your government for detailed information on any specific entry restrictions or health recommendations in each country.
Wi-Fi is widely available in hotels, cafes, and public areas in Zurich, Lucerne, Interlaken, Luxembourg, Paris, Milan, and Venice; however, it's advisable to check for any potential login requirements. Cellular coverage is robust in urban areas, but may be spotty in rural regions. Consider purchasing a local SIM card upon arrival for better data access. Power outlets are generally Type C or F with a voltage of 230V; travellers should bring a universal adapter for compatibility with their devices.
