Nearly 75% of cabins on an 128-day around-the-world epic cruise unveiled last month by Regent Seven Seas have been booked within hours of line's announcement, even though the price tag exceeded $100,000 per couple.

The news was revealed this week by an executive for the parent company of the luxury line in a conference call concerning second quarter earnings.

President and CEO of Norwegian Cruise Line Holdings (NCLH) Frank Del Rio said during the meeting with Wall Street analysts, that the cruise had proven so popular that more than 70% of it had been booked on the first day of sales. He added that was a testament not only to the Regent brand's allure, but also to the belief that company's guests wanted "unique, different, and rich destination experiences".

Norwegian Cruise Line Holdings is parent company of Norwegian Cruise Line (NCL), Oceania Cruises and Regent.

Kicking off January 5, 2017 in Miami, the grand sailing on the all-suite 490-passenger Seven Seas Navigator will be the first Regent around-the-world cruise in 6 years, as well as one of the most ambitious projects of the line ever. It includes stops in more than 60 cruise ports across 6 continents.
