Paris, where more than 100 people were killed in November, has likewise not been immune to fallout from the recent attacks. Data compiled by the National Institute of Statistics and Economic Studies found that overnight stays among foreign travelers declined 6.3 percent there during the first quarter, as compared with the prior year.
Separate data from the Paris Convention and Visitors Bureau found the hotel occupancy rate there fell 6.2 points during the first quarter, to 61.7 percent, compared with the first quarter of 2015 (when the attacks against Charlie Hebdo, the French satirical magazine, took place).
Yet such drops are often short-lived, Scowsill said. Back in 2002, when a nightclub bombing in Bali killed more than 200 people, the tourism industry initially cratered; but it began to recover roughly a year later. Likewise, a spokesman for the Paris tourism bureau said the organization "could feel there was a slow recovery" in the city during the first quarter. Still, he cautioned April is expected to be weak due to the shift of Easter into March and the city's proximity to Brussels, where three coordinated nail bombs went off in April.
Though Scowsill predicts there will be a few weeks of people hesitating before booking a trip to Orlando, he does "not expect a huge amount of cancellations" for already planned trips, he said. That's because law enforcement and the local government quickly and effectively communicated information about the shootings, which were put to a stop when the suspect was killed.
Damian McCabe, CEO of McCabe World Travel, said her firm does not have "any comment beyond that we don't anticipate this sad event effecting tourism to Orlando in the long run."
A spokesman for Delta Airlines said the company has not had a change to its Orlando flight operations since the shooting. At JetBlue Airways, a spokesman did not say whether the airline has seen any cancellations on flights to Orlando, but said it is providing free seats on available flights to and from the area for immediate family and domestic partners of victims who were killed or injured.
A spokesman for Universal Studios, which like CNBC is owned by NBCUniversal, said "the safety of our team members and guests is always our top priority — but we do not discuss the specifics of our security plans and procedures."
Walt Disney World said in a statement, "Unfortunately we've all been living in a world of uncertainty, and during this time we have increased our security measures across our properties, adding such visible safeguards as magnetometers, additional canine units, and law enforcement officers on site, as well as less visible systems that employ state-of-the-art security technologies."
