Norwegian Cruise Line Holdings announced earlier this week it was dropping vaccination requirements on cruises from the U.S., as well as pre-cruise related testing protocols for vaccinated guests. The result? Cruise bookings picked up.

“(The) announcement was an instant catalyst, resulting in one of our top three best booking days of the year,” said Frank Del Rio, president and CEO, speaking on the company’s second quarter earnings call.

The company will no longer have a mandatory vaccination requirement on any of its ships, which include the Norwegian, Oceania and Regent brands.

Del Rio said the company had relaxed testing protocols, regardless of sailing length.

“To put it simply, vaccinated individuals, including those embarking on NCLH ship from U.S. ports will no longer have any pre-cruise related protocols, and those who are unvaccinated or choose not to provide proof of vaccination will be required to test negative within 72 hours prior to embarkation. In addition, all guests 11 years old and younger will be exempt from vaccination and testing requirements of any kind,” he said.
