The financial crisis in Greece prompted the British Government to advise UK citizens traveling there to take plenty of cash, in case difficulties emerge getting money there.

U.K.'s FCO (Foreign and Commonwealth Office) advised British travelers to bring enough euros in order to cover daily expenses and emergencies.

The statement from FCO said that while banks were closed in Greece and withdrawals were limited, travelers had to make sure to take sufficient euros in cash to cover their stay's duration, emergencies, unexpected delays and unforeseen circumstances. Travelers should also "take appropriate security precautions against theft". Currently, there are no restrictions on taking unspent money out of Greece at the end of stay.

Greece is in severe financial crisis due to its failure to meet debt obligations. A referendum was called for July 5 and citizens will vote on whether they want to stay within the Eurozone or go with currency of their own.

Plenty of news stories reported tourists finding ATMs without funds, as Greeks are pulling money from their bank accounts. All citizens are limited to 60 Euros per day (about $67). Associated Press reported that some stores rejected credit cards, and travelers heading to Greece had to bring euros with them.

Meanwhile, cruise lines continue their itineraries to Greece as scheduled. Costa Cruises, Celebrity Cruises, NCL Norwegian, Princess and Royal Caribbean are all sailing to Greece this week with unchanged plans.

Windstar sent its guests a message, letting them know that foreign tourists could still use their international bank cards at ATMs. Only Greek nationals are currently under daily withdrawal limitations. The line also noted that U.S. credit cards were still accepted at lots of places.
