NEW YORK —Tourists on holiday in Greece offered advice to others Monday: Bring extra euros.

Several reported having some anxious moments over the weekend thanks to empty ATMs and merchants refusing credit cards, but the inconveniences eased as ATMs were replenished Monday.

“We were finally able to get cash out of an ATM today, thankfully, since we are running out of euros we got in the U.S.,” said Anthony Adornato, a college professor from Syracuse, New York, heading from Athens to the island of Kea with three other Americans. “We thought we would have to start rationing, but luckily found an ATM that worked after two days of having no luck with others.”

They’d tried five ATMs before finding one with cash, and many merchants had refused to take their credit cards.

Richard Joplin, a realtor in Austin, Texas, arrived in Athens Monday with his two daughters for a 10-day holiday. “So far we have only been inconvenienced with restaurants and cabs only wanting cash,” he said. “I brought euros with me for that reason.” But he didn’t bring enough to last the trip, and hoped he’d be able to use credit cards and ATMs later in the trip.

But others reported no problems. “So far so good because we’ve only been here for a day and came with a lot of euros,” said Chloe O’Brien, 21, of New York City, traveling with her grandma and two aunts to Athens and Mykonos.

Laura Simoes, visiting Kefalonia from New Hampshire, said she had “neither seen, nor felt, any impact from the economic crisis. … Nearly every market, restaurant, etcetera has taken our credit card and never suggested they’d rather have cash.”

Greeks can only withdraw $67 per account daily from banks, but the limits do not apply to foreigners.

The tour group company smarTours, which is sending several groups to Greece in a few weeks, is not seeing cancellations and is simply advising clients to bring euros.

SmarTours spokesman Greg Geronemus said, “At this time, we do not believe that travelers are at risk, but this is a fluid situation and we are monitoring it very closely.”
