We booked a 10 day cruise in Svalbard for June 2020 so it goes without saying that the ship design doesn't concern us. The zodiac loading setup on the Mortimer seems to be well thought out & efficient. In theory, that should mean more time away from the ship and closer to the sites / wildlife.
Also, the price for Svalbard was about 40% of what we paid for a Silver Cloud Expedition cruise to Antartica earlier this year for the same class cabin and length of cruise. Granted, there is and should be a price difference between four & five star service levels .... but still, it's significant .... and eating six course meals every night was never the motivator for an expedition cruise.
Of course we are hoping the previously expressed concerns about the ship delivery don't materialize.
Hope to have the good fortune to see some of you on board.
