Check card fees
Foreign-transaction and cash-advance fees can change the real cost.
Have redundancy
A second card or payment method can help if one issuer blocks a transaction.
Keep methods separate
Do not store every card and cash source in one wallet.
Use current exchange rates for budgeting
Budget cushions matter because rates and local prices move.
Verify before you go. Weather, entry rules, advisories, transport schedules, prices and local conditions can change. Use this page to structure your decision, then verify the current details that affect your specific trip.
