Cruise lines are so far taking a wait-and-see approach to the economic turmoil in Greece.

Several lines with itineraries that include stops in Greece said they continue to sail those itineraries without substituting alternate ports.

Brad Ball, a spokesman for Silversea Cruises, said that there are no changes to its itineraries at this time. The line's Silver Spirit and Silver Wind ships are currently doing seven- and 10-day Mediterranean itineraries with stops in Corfu, Santorini, Mykonos and Rhodes.

Summer is peak season for cruising the Greek isles and with the exception of Carnival, most cruise lines have seasonal deployments there.

"As of now, there are no changes," said Jason Lasecki, a spokesman for Prestige Cruises, parent of the Oceania and the Regent Seven Seas brands. "We're continuing to monitor the situation."

Likewise, nothing has changed with regards to Greek ports of call for Royal Caribbean and Celebrity Cruises, said spokeswoman Cynthia Martinez.
