For honeymooners, vacationers and business travelers alike, Greece's problems have added an unexpected kink that requires some additional thought and planning. Not many are canceling or altering their plans now, says Gabe Saglie, senior editor of, but there are some precautions to take.

Normally when there is reason to believe a trip might be interrupted, experts would suggest travel insurance. But these policies mainly deal with routine snafus like lost luggage rather than a nation's economic woes. "Probably the only trip insurance that would cover you is 'cancel for any reason,' which pays back a percentage," says Christopher Elliott, author of the book "How to be the World's Smartest Traveler."

These policies average around $500 and reimburse you for 50 percent of non-refundable expenses. AIG, for instance, offers insurance that would cover a couple's trip next month from New York to Greece. The price, which ranges from $362 to $756, includes coverage for a trip operator going defunct.

Manage your cash
To avoid an immediate cash flow crunch, editor Jason Cochran suggests avoiding banks in Greece, which have rationed money and drastically reduced their hours. That means carrying enough euros with you and relying on credit cards.

Not all places will accept American Express, he adds, so use Visa and MasterCard instead. Also assume you will not be able to use your ATM card while you are there.

Travelzoo's Saglie suggests carrying prepaid cards, and once there, using hotel safes and deposit boxes to stash valuables you do not want to carry with you. "Be discreet with your cash and refrain from drawing unwanted attention to the cash you’re carrying," he says.

Plan ahead
For those with a longer planning window, the outlook is mixed on whether Greece will be a travel bargain anytime soon, Saglie says. But both he and Cochran note that Greece's problems had pushed up the dollar's value, benefiting all U.S. travelers visiting Europe.

"If Greece does, in fact, exit the euro and resurrect the drachma, that currency would also likely be devalued, making Greece an even bigger travel bargain," Saglie says.

For those who still do not feel quite comfortable enough to travel into the midst of an economic crisis, there are alternatives, like the Mediterranean coast of Turkey or a cruise.

"You can experience a similar cultural history, including ruins and a festive beach life," Cochran says. "But summer is high season for Mediterranean cruises, so don't expect a bargain on those."
