Past Cruise Itineraries

Is there a place one can get past cruise itineraries?

Does O repeat cruise itineraries every other year or on some type of other rotation?

There is a cruise in January of 18 we really like but don't want to go till 2019 as a retirement gift. Any thoughts?

Thanks

What cruise is it? Many itineraries are repeated regularly - some with minor changes. Others are less common - like the circumnavigation of Australia.

Sorry should have been more specific.

We've been on this itinerary before - so they have done it at least once before (and maybe more).

Not the most common one - perhaps you should try to go?
