Doris, we just booked the BA-Santiago segment with Susan Walsh and had the same ? having not
sailed the Mariner..here is what Susan wrote:

I think 748 is great. The Mariner has no inherent (vibration) problems like the Navigator.

PS..per email I received from Marc Conroy today, Regent will fix the Pod problem on the Mariner 5-15 Jan 09 (pls see below)..thus we will not have any itinerary delay/change problems (due to slow speed) on the Mariner

Dear Col. Weiner,

Actually it will be replaced in a dry-dock which will take place January 5 to 15 2009 just after the New Years cruise.

We will take the damaged pod off and replace it with a new one and then take the damaged one and repair it and hold it in storage as a spare.
