The ideal approach involves a combination of forex cards and cash:
Forex Cards: A forex card, such as the BookMyForex Multi-Currency Forex Card, is the most economical way to carry the majority of your funds (70-80%). These cards offer zero markup interbank rates, protecting you from exchange rate fluctuations. They are also secure and convenient, allowing you to make transactions without carrying large amounts of cash.
Currency Notes: Keep some cash on hand for situations where cards aren't accepted, particularly in smaller establishments or remote areas. It's a good idea to carry a mix of denominations to cover various expenses.
