How does money, currency exchange, atms and cards change when travelling with children or luggage?

Cash remains useful, while cards and mobile payments are common at larger businesses. Compare exchange rates, decline poor dynamic currency conversion and protect cards and PINs. Space, seat belts, walking distance, heat and transfer points become more important. A slightly more expensive direct service may be better value for a family or heavy luggage. Confirm child seats, baggage limits and the final drop-off rather than assuming they are included. Money note: Exchange rates, ATM fees and card surcharges change. Compare the net amount, decline poor dynamic currency conversion and keep transaction receipts.
