Is it better to fly or take the train?

If the travel time is 4 hours or less by train, always take the train. It drops you in the city center, avoiding the cost and time of transit to/from airports.

How do I handle varying currencies?

Use a travel-friendly debit or credit card with zero foreign transaction fees. Most of Europe (including all major business hubs) is now almost entirely cashless.

How to plan a multi-city business trip through Europe

To plan a multi-city European business trip, book a 'multi-city' flight ticket to avoid backtracking, prioritize central hotels within walking distance of business districts, and use high-speed rail instead of regional flights to save time and stress. Always schedule a 3-hour buffer between meetings to account for transit and city navigation.

Map your sequence logically. Group your cities geographically to avoid zig-zagging. Use a tool like Google Flights' 'Multi-city' search function to test different sequences. Plan to move in one direction (e.g., London to Paris to Frankfurt) to minimize travel time.
Use high-speed rail for intra-Europe travel. For travel under 4 hours (e.g., Paris to Brussels, or Amsterdam to Cologne), always take the train. You skip the 2-hour airport arrival requirement, security lines, and the commute from outer-city airports to the city center.
Book hotels with 'Business Center' amenities. Filter hotel searches specifically for 'workspace' and 'reliable Wi-Fi'. Avoid boutique hotels in quiet residential areas; stay within a 15-minute walk or a single train/metro ride of your meeting venue.
Standardize your documents. Create a single digital 'master folder' (on Google Drive or iCloud) containing all boarding passes, hotel confirmations, and meeting addresses. Download these for offline access in case of data roaming issues.
