The reviewer "Regent Ain't What She Used To Be" provides a detailed review we entirely agree with. Unlike that reviewer we had not sailed with Regent before. Our cruise experience was with Seabourn. We believed the two cruise lines were similar. In our experience they are not.
Seabourn prides itself on the interaction between staff and clients - this is the major failing we found with Regent. As noted by other reviewers, staff seem overworked and undertrained. Many categories, such as the sommeliers throughout the ship, are sommeliers in name only. They could offer, poorly, the wine of the day, but struggled to deal with any request beyond that.
More generally we made a number of inquiries with staff, none of which were adequately dealt with. The answer typically was "I don't know", there was no offer of follow up or further assistance.
Compared to Seabourn the food was ordinary and very repetitive. Typically we left most of it on our plate.
Other guests we befriended, who had travelled with Regent previously, bemoaned the fall in standards.
We agree with comments in other reviews about the time consuming, frustrating, process of allocating clients to excursions and disembarkation. Put simply there seems to be a lot of double handling and lengthy delays. All tour allocations are funnelled through one person who seems easily distracted. On one occasion a guest arrived very late for a tour, the organiser left a theatre full of other clients while he dealt with this one latecomer who, given the circumstances, should have been left behind. If you arrive 20 minutes after the departure time for a tour it is unreasonable to have any expectation of being on that tour.
We would not travel with this cruise line again.
Cabin was ok.
