Also not factored into the equation, Gold points and past passenger deduction. I didn't check the Radisson cruises to see if they qualify for SSS discounts but combined with Goldpoints, that is a nice deduction from the Radisson cruises. I have never sailed Silversea so I would not get any further deductions.
