My husband and I have sailed with Regent (formerly Radisson) twice before - Alaska 04, and the Panama Canal 05, both on the Mariner. The Baltic cruise in June 06 was our first one on the Voyager. I have seen lots of postings on the boards asking for comparisons between the two. Quite honestly, I think they are clones! The same wonderful suites, excellent service and superb food. I think the only negative about the Voyager versus the Mariner is that there is indeed vibration aft! But we were forward and heard and felt nothing.
We boarded in Dover. We live in Switzerland and travelled to London three days before, staying at the Milestone Hotel in Kensington. This is a wonderful hotel and its standards mesh well with those of RSSC. We hired a car on the Sunday and drove to Kent where we visited some lovely gardens and stayed in a terrific B&B (The Olde Moat House). I dropped my husband and the suitcases at the Cruise Terminal in Dover and returned the car to Hertz (not such great service, at least at the Dover end. There is no shuttle to the Cruise Terminal and the woman was most unhelpful! Fortunately, I know Dover and was able to walk to the station and get a taxi there!!)
Our luggage was taken from us and we were ushered to a large waiting area, with comfortable seats. After about a 15 minute wait - they were dealing with passengers in small groups - we went through security and boarded the Voyager.
