Saga operate two shipping companies - Saga Cruises and Quest for Adventure. Since it's foundation in 2005 QofA has operated the Spirit of Adventure (ex-Berlin) with the original plan to add the Quest for Adventure (ex-Astoria).
However, with the retirement of Saga Rose the plans were changed and the old Astoria was brought into service with Saga Shipping as Saga Pearl 2.
Now .... with the introduction of the Saga Sapphire, Saga Pearl 2 will transfer to Spirit of Adventure Cruises as ( ....pause) Quest for Adventure.
I'm not sure what the future plans are for the Spirit of Adventure.
Whist Saga Cruises are aimed at the 50+ market (so that rules Colette out!

) the age limit for Quest for Adventure Cruises is 21+.
