While Regent was very nice, the general vibe was more reserved and less casual. The cabins were very nice. Service good. The food was not as good. The low point were the included excursions, which were good to absolutely terrible. This was 2019 pre Covid. They were sometimes outrageously misrepresented as to itinerary and activity level.
Several of the tours marked as easy, required miles of walking, ( I wear a fitness tracker) very rough terrain and in one case getting into some giant all terrain vehicle ( called a jeep in the description) the first step being as high as my shoulder, no step or help from the tour operators. After two or three very uncomfortable experiences, I started dreading what would be next and canceled several. They were not all bad, but enough that were a long glorified bus ride or ridiculously catagorized as to physical ability. Another aspect of the included tours that I did not consider, was many sea days and loss of several ports due to various reasons. This significantly reduced the overall value.
If you are a drinker, you will not find yourself lacking. One couldn’t sit down for 3 minutes without being offered or many times just handed a drink. After a day or two most servers knew I liked a glass of white wine and I was served one without asking in minutes.
This was my only Regent experience and it was in their newest ship.
I have done many more on Oceania and overall I prefer them, particularly the smaller R ships.
