It is advisable to take at least two forms of money with you when travelling.
Credit cards and debit cards are increasingly accepted overseas and are a convenient and safe way of obtaining money via ATMS. It is also advisable to take some cash as ATMs do not always work and may not be available in out of the way locations. Money supplies should be kept separate in case of loss or theft.
