Here is the SilverSeas description:
To Silversea, our returning travelers are more than our guests. They are a part of a private club of distinguished guests who have sailed with us in the past and share a love for cruising – and thus become exclusive members of the Silversea Venetian Society. This extraordinary club of travelers enjoys exploring the world in luxurious fashion while receiving members-only benefits and privileges. We look forward to welcoming you to the club.
Membership in the Venetian Society is automatic upon completion of your first voyage onboard any of the Silversea ships. You will then begin accruing Venetian Society cruise days, and are eligible for a number of benefits and privileges.
5% or 10% Venetian Society Savings on Select Voyages
Onboard Recognition and Private Parties

Select Offers through Silversea’s Preferred Partners, chosen to complement your discerning lifestyle.
Through our Friends of Society programs you can double your cruise days and receive an onboard shipboard spending credit if you invite friends or family to sail with you on select Venetian Society sailings. Your friends or family will enjoy the same Venetian Society savings you do.
They have benefits that create classes such as early disembarkation. They also have on 5% or 10% discounts on "select sailings." They don't talk about priority for dining or spa.
