Concerned clients have called about the protests in Athens spurred by the country’s economic crisis, but tour operators say that cancellations are rare.

"Honestly, we have not had a single cancellation, which is wonderful," said Fred Berardo, president of Central Holidays. "I was expecting it to be different because of what they show on TV. The media are showing it like riots."

Central Holidays' 2011 Greece bookings have increased, but not as much as Berardo originally had hoped — but not because of the country’s political and economic problems.

According to Berardo, the stalled U.S. economy and rising airfares have impacted growth more than anything else.

"The images you see are much stronger than what is [actually] happening in Athens," said Ronen Paldi, president of Ya'lla Tours. "It is important for the people abroad to understand that these images are the result of the action of 200 young people and do not represent the Greek people."

Both Paldi and Berardo predicted that the situation in Greece will soon improve now that an austerity measure has been approved.

One cruise line, Voyages to Antiquity, is using a hotel farther away from protests for guests arriving for a pre-cruise stay on July 1 and for guests who purchased a post-cruise package early next week.

Mitchell Schlesinger, Voyages to Antiquity's vice president of sales and marketing, noted that the protests have been confined to one part of Athens.

"We have a phenomenal ground operator in Athens, and they take great care of our passengers," he said.

Schlesinger said protests are expected to die down. "The folks in Greece are known for their short-term reactions," he said.

Voyages to Antiquity operates the 350-passenger Aegean Odyssey. The ship will arrive in Athens on July 4 and depart that night for an eight-day cruise to Istanbul.

CORRECTION: The Aegean Odyssey's capacity is 350 passengers.
