I will not review the ports as they are covered regularly by others.
The company my wife works for chartered the ship for a special 6 day northbound Alaska cruise. We were 352 on a ship that is designed to carry 490. Don't know if the line used the smaller passenger count to grant furlough to some extra employees, so some of my comments may not be applicable to a "normal" cruise. For example: our category B suite normally comes with a butler; we did not have one.
In general, we enjoyed the cruise and the pluses outweighed the minuses by far.
The ship itself is a strange looking vessel that i thought was less attractive than more traditional ships, but I know that beauty is in the eye of the beholder. Once aboard, the decor is pleasing and muted, with some areas looking well worn and in need of attention. Not shabby, but not up to snuff for an upscale ship.
And that describes my overall feeling about the cruise.
The cabin stewardess was efficient and friendly, but requests were handled as a one time event rather than a preferred, on-going request. In room coffee pods for example, were only refilled when we asked. We asked every day. The toilet had a bath and a shower, and superb toiletries by Bulgari. This opulence was balanced by the cheapest toilet paper I have ever used in my life. Sam's Club is better.
Food was universally good and professionally served. Menu choices were adequate but not noteworthy, with some unusual items. Cruising in Alaska with it's famed seafood and the one night (only) lobster was offered... was Florida lobster. Why ? Also, In both restaurants the wine steward regularly offered refills of your chosen wine, but we had to ask for water or coffee refills almost every time we ate. Again... a mixed message. I know that other nationalities do not drink water/milk/coffee/soda during meals but this ship serves a predominantly American clientele for much of the year.
Breakfast had a wonderful, bountiful, cornucopia in the buffet, with attendants to serve. But only one chef/cook to handle egg requests. Delicious but oh-so-slow.
Two percent milk was provided for coffee in every venue. Cream was not available but the server would trot back to the galley to get half and half if one asked. 2 percent milk ?
Now for the positives:
I loved the small scale of the ship. Everything is near by and decks are served by the fastest elevators at sea. Never... Never ... waited more than 5 seconds for an elevator. The compact size allows public room placement to be a non-issue, and getting on and off the ship was a pleasure every time.
The all-inclusive style used by Regent Seven Seas is a gift from the gods. Booze, soft drinks, shore excursions (some not all ), gratuities and the like are simply not an issue. Not once all week did I have to produce the cabin card to buy something.
Not much of a gambler so the casino wasn't visited.
Room service breakfast is full menu and full service. The attendant sets up a full height table with linens and silverware. Classy.
The Captain and senior officers were visible and approachable every day. When was the last time a ship's Master approached you to shake your hand ? In my case, not once in 16 cruises, but it happened on Navigator.
In closing, I reiterate that we enjoyed the cruise very much and would sail on this ship again in a heartbeat. Not sure it's worth the premium pricing, however, since there were hiccups in service.
