Despite its economic turmoil there is no reason to avoid Greece, but you need to be prepared.
Here's how it looks at the time of writing. The €60 a day limit that applies to Greek citizens withdrawing cash at ATMs does not apply to those holding foreign banking cards. However, there is a chance that ATMs might run dry.
As far as possible, pay for accommodation before arriving in Greece since some travellers are reporting that a few hotels and restaurants are insisting on cash payments.
Panic buying of petrol has resulted in queues at service stations on some islands and travellers intending to hire vehicles need to be wary of potential tightening of supply.
As long as there are tourists to be served, there is little chance that Greece's ferry system, which is privately owned, would stop operating.
Some supermarkets are reporting shortages of basic food items due to panic buying but there is no indication that the tourism sector has been affected.
Take a reasonable supply of euros in cash, and check your travel insurance policy to find out how much compensation you are eligible to receive in the event of loss.
There is no cause for fear. If you were to cancel a trip to Greece due to concerns over security or Greece's economic woes, your insurer would be under no obligation to offer compensation.
Tourism makes the Greek economy go round, and the best thing you can do for Greece now is to holiday there.
