Nine free interactive tools that answer the questions you actually ask before booking — visa, budget, trains, the Wall, payments. No sign-up, no app install, no tracking.
Answer the booking questions first: can I go visa-free, what will it cost, and is my window a mistake.
Turn the route into day-by-day plans and check the trains between cities.
The two setups that make or break the trip — payments and your phone — plus the translation layer.
