Silversea Cruises has extended an offer of $500 per couple on board credit in a bid to boost early bookings.
The deal now covers 26 new voyages in 2011 based on bookings made by March 31, 2011.
The $500 shipboard credit can be used towards shore excursions, spa treatments, premium wines and spirits, specialty restaurant dining fees, purchases in the internet café and onboard boutiques.
It applies to selected departures by Silver Cloud, Silver Shadow and Silver Whisper.
UK and Ireland managing director Trudy Redfern said: “Our $500 shipboard credit offer has been extended to dozens of sailings across the globe in 2011, including the Caribbean, South America, Far East and South Pacific.
“Depending on availability, the shipboard credit can be combined with a host of other incentives, such as silver savings and free air programmes – making this the perfect time to firm up travel plans for next year and enjoy substantial savings.”
