Royal Caribbean International has claimed sales for its expanded 2011 European itineraries are up by more than 50% in the peak new year ‘wave’ selling period.

The line said the figure was based on early indications on sales compared to the same time in 2010. UK and Ireland vice president and managing director Dominic Paul said: “Our decision to continue to invest in the marketplace shows all signs of paying off.

“This summer we will have 11 ships based close to the UK around Europe, offering a huge variety of great value holidays, and this is driving a significant increase in sales.

“Our new ‘What you see is what you get’ campaign is resonating well with both consumers and trade partners, and we are delighted with the support we’re receiving from the trade. We remain cautiously confident that the positive start to the year will set us in good stead for the remainder of 2011.”

The line has positioned Grandeur of the Seas in Palma for the first time in a move that is attracting a “solid number” of first time cruisers, Royal Caribbean said.
