The luxury line is offering upgrades, free onboard spending and discounts on a second suite as part of the campaign which is available for new bookings from June 1 to July 31, 2016, on selected cruises running later this year.

Clients can receive $1,500 per suite in free onboard spending for ocean cruises or choose from a two-category suite upgrade or 50% off a second suite.

For selected expedition cruises, including some itineraries to the Galapagos islands and Antarctica, guests can choose from a two-suite upgrade or a half-price second suite.

Lisa McAuley, Silversea’s commercial director UK and Ireland, said: “Silver Select gives travellers an a la carte menu of several generous savings opportunities, each providing outstanding value.

“Guests can treat themselves to a larger suite, or indulge in personal pampering at the onboard spa. Plus, the option of a second suite at 50% off provides incomparable savings and the opportunity to invite family and friends to holiday with you.”
