The savings are available on Mediterranean sailings with departures between August 1 and September 19.
The cruises available are all all-inclusive with everything from flights and excursions and drinks and wifi included in the price.
Regent Seven Seas Cruises managing director Graham Sadler said: “The beautiful ports of the Mediterranean are not only the perfect backdrop to showcase this stunning ship, but are also only a short flight away for many of our UK customers.
“I am sure that our guests will love the newly sparkling fine-dining restaurants, convivial bars and lounges and luxuriously appointed suites.”
The sale comes following a 25-day refurbishment in November 2016 on the Seven Seas Voyager as part of a $125 million ongoing fleet-wide refurbishment programme.
