Travelers are debating whether to stay in hotels or hostels for their trip to Amsterdam, Florence, Venice, Rome, Madrid, and Barcelona, considering cost and privacy. It is advised to avoid carrying large amounts of cash, such as $2000, and instead use credit cards for better exchange rates and security, as they are widely accepted in these cities. Travelers should ensure their ATM cards will work in Europe and notify their banks of their travel plans to avoid issues. Recommendations for exploring local attractions and dining options beyond the typical tourist spots are also sought. Engaging with the local language, even minimally, can enhance the travel experience significantly.
