What is advertised as the Mariner WC is really just a combination of the South America and the Ring of Fire cruises, except for the leg from Valpariso- Auckland, which should really be a great cruise. Too bad they are invoking the new smoking policy. If they hadn't done that we'd be going on the 24 day leg. However, Silversea has a similar leg as part of the 2008 Shadow WC.
