I thought you were comparing Regent Mariner and Voyager to the Navigator Christmas and New Years cruises. Per diems on the holiday cruises on M and V are less than on the Navigator with balcony.

Comparing Regent prices to SS is almost always an eye opener. Silver Shadow per diems for the 14 day Christmas/New Year's cruise for Verandah are $719, v. $412 for Voyager, and $428 for Mariner! Navigator slightly more as they are shorter. It baffles me that Silversea can fill ships at those prices, as I can't tell the difference between the lines from my one experience on SS, which was very pleasant, BTW! I got a fair deal back when I booked my one SS cruise, and plan to be on Whisper with Ngaire on our group cruise (CAMEL) in May for Dubai to Athens, which is just a little less (for balcony cabin) than what Regent charges for almost the same itinerary on the Navigator later in the year. Plus, we get our sweet BK rewards check with our docs that will provide a good bit of shopping money for Dubai!
