Royal Caribbean has begun its seasonal "wave campaign" sale in the United Kingdom, with up to $1,000 on-board credits available.
The sale begins on December 10 and runs through February 28, 2013 and includes flights starting at £59 to connect to ships sailing from other European ports.
Those that book into the sale can find free balcony upgrades on select European and worldwide cruises.
Head of trade sales Nicki Tempest-Mitchell said: “We are offering up to $1,000 for bookings made during the turn-of-year campaign, which is massive and the largest added-value booking incentive we’ve ever done.
Promotional cruise prices lead in at £1,149 for a 12-night Baltics cruise on Adventure of the Seas in June 2013, including up to $1,000 on-board credit per cabin.
