Travel Tips
Practical guides for the planning questions that sit between choosing a destination and actually getting there: how tickets and passes work, what tends to cost extra, and how to pace a trip so travel days don't swallow the holiday.
Each guide links to the official sources behind its rules and shows the date those rules were checked. Example budgets are planning models, never live fares — confirm prices for your own dates before you book.
