Wanted to try a high end cruise to see if Regent was better than my other cruises -- in a word, Regent is far below their competitors. In the past six years I did an Alaska cruise on Celebrity. I had an aft cabin and we had our own restaurant (Blu). All meals were ala carte, served fresh, hot and delicious. The price, as I recall for a 9-night cruise (instead of the 11 on this sailing) was about a third of Regent's price. Then I did two European river cruises on Avalon. Of course there is a much smaller number of guests on a river cruise, but every meal had a half dozen of ala carte meals, paired with very good wine.
This brings us to our Regent Mariner experience. First of all, the pros. The ship was exceptionally clean, the staff was very friendly, the cabin was nice, unless you sleep on the left side of the bed like I did. If you get up to use the loo in the middle of the night, always remember that there is a wall facing you about 10 inches from your bed! There is a great Coffee Connection place where they served liquored coffee drinks and snacks, enjoyed that immensely.
Now, one of the main things you go on a cruise for is good food, right? Overall, the restaurants were a major disappointment. The two "specialty" restaurants, Prime 7 and Chartreuse, were only made available one time during an 11-day cruise. Big mistake by Regent. We did eat there twice after going to see the concierge but they make you wait until 8:30, much later than we like to dine.
Very clean and well kept up by the steward and cleaning crew. Very satisfied about this.
