Not so fast, tour operators

Despite the easing of travel restrictions to Cuba, US tourists won’t immediately be bellying up to the bar at Havana’s famed watering holes.

A ban on commercial tourism from the States remains in effect despite President Obama’s plans to reestablish diplomatic ties.

But the dramatic move still gives hope to travel companies that they will be able to cash in by luring American travelers to Cuba, already a hot spot for sunstarved Canadians and Europeans.

“Cuba is the largest country in the Caribbean, so there are some exciting possibilities,” said Roger Frizzell, of Carnival Cruises. “Some infrastructure for cruising already exists in the country, along with several ports, so it offers great potential.”

US airlines have also been eyeing Cuba as a moneymaker, with several already offering charter flights for Americans with approved educational or journalistic affiliations.

JetBlue started flying Cuba charters in September 2011 for those allowed to travel there under current regulations.

“We look forward to the day, hopefully soon, when all Americans have the opportunity to travel to Cuba,” said Barney Harford, of the travelbooking site Orbitz.

The country was once a haven for sunseeking Americans and celebs — including the late author Ernest Hemingway, who had a reserved seat at El Floridita bar.
