Ultra-luxury Silversea Cruises has expanded its Silver Select promotion beyond Alaska and the Mediterranean to include 21 additional sailings in the Caribbean.

The Silver Select promotion enables guests to personalise their voyage with a choice of three enticing offers: a two-category suite upgrade, a £300 per person credit towards the purchase of the Silversea Air programme, or a $500 per person on-board credit that can be used for shore excursions, spa treatments, speciality restaurants and more. Silver Select is available on new bookings made by 31st August 2014 for select voyages sailing in the Caribbean, Alaska and the Mediterranean.

“Silver Select’s three generous savings options have proven hugely popular, and we’re delighted to be offering them now on voyages to the beautiful, sunny islands of the Caribbean,” said Mike Bonner, Silversea’s UK General Manager.
