We chose this cruise for the itinerary and because we had heard that Regent was a 5 star experience. Our last cruise was on Oceania Nautica and we had absolutely loved it. We decided to try Regent with it's all-inclusive liquor and excursions.
First, what we liked: Our cabin was great (Penthouse with a fabulous butler). The all-inclusive liquor meant we didn't feel nickel-and-dimed at every turn. The room attendants were incredible and the destinations team were very helpful. I loved Marla, the Social Hostess and Terry Breen, the guest lecturer.
And what we didn't like: Meals could go on forever, since there didn't seem to be enough waitstaff to bring the courses. The waitstaff was uneven, as well - some were attentive and helpful (thank you Gianluca, Tomaz and Federica!) and others seemed to be waiting for their shift to be over, while providing the minimum amount of attention. And the food was also uneven. For example, in the beginning, the hollandaise sauce was pretty good. After the first week, they forgot how to make it and served a tasteless, gloppy substance. Whatever happened to the lemon juice? I also admit that I really missed the Lido on Nautica. There was no place to have a completely informal meal in the evening - all the restaurants had dress codes. That's fine, but sometime you just want a plate of salad after a day of excursions!
The cabin was very nicely appointed. We liked the walk-in closet and the furniture was quite comfortable. The safe was a little shallow, but we adapted. There was an espresso machine that we used occasionally.
