We put three cruises together starting in Dublin 7/18 and disembarking in Barcelona 9/1.
The positive was the crew and service was excellent for the most part.
The negative is extensive. The ship was not particularly stable with a good deal of pitching and rolling in calm to moderate seas. Vibrations at the stern were noticeable even on the 10th deck. Some people in cabins at the rear portion of the ship demanded new cabins.
The food was mediocre for the most part. The signature Prime steak restaurant had to recook a medium rare filet on two occasions. Surprisingly there was little local food and wine as we cruised Scandinavia and Europe. Wines were focused on primarily US wines and frequently ran out without resupply.
The ship docked most of the time a significant distance from the actual place we were visiting. Long bus rides were the standard and cabs back and forth were extremely expensive.
Tours were clearly not designed with the guest in mind but for the convenience of the cruise line. Many times tours were scheduled when venues or cities being visited were not open. the maddening thing was there was adequate time to run the same tour a few hours later in the day without impacting the scheduled departure times. Many times the "free time" did not occur due to the guide not managing the tour properly. 75% of the guides were substandard compared to other guides in Europe and on river cruises.
It was a very expensive experience with such a negative result. Many people with hundreds of cruising days on Regent were complaining about the lack of quality on the cruise as compared to their other experiences.
Plenty of storage space. Comfortable bed. Sofa was in need of replacement. Difficult to sit on with the front of the cushions being crushed and the fabric being slick.
Routine maintenance in the bathroom was needed for several items and they never could get the shower drain clear so you weren't standing in an inch of water as you showered.
