My wife and I had a terrific time on the cruise. We were impressed with the ship, the service, the facilities and the food. I won't repeat what others have said about the ship itself: very deluxe, beautiful public areas, well laid out except for the performance theater. Service was superb. Food was diverse and excellent. Organization for embark and disembark were excellent. We could not be more pleased.
A few notes to add to what others have said:
Itinerary: Regent changed the itinerary to replace Egypt with some more Greek islands. This was a big disappointment to us, as we had chosen this cruise in part because of the stops in Egypt. While safety concerns are understandable, there was nothing in particular of concern going on in Egypt at the time of our cruise. And Regent gave notice of the change at a time (to the day!) when cancellation penalties would be significant. Not good. We decided to make lemonade out of lemons by taking a side trip to Athens while the ship made island stops. We asked Regent to make the arrangements and they did an excellent job. The two days in Athens and transport to and from the ship when off without a hitch and were most enjoyable and interesting. Yes, it cost us some money but it was worth it. Fellow passengers were jealous of us that we had done this. Perhaps Regent should have. offered this as an in-cruise extension to all.
Internet: Much has been said about the Wifi and I will add the following: In 2016, having Wifi and reliable internet connectivity is frankly a utility like indoor plumbing. It is no longer a novelty and something vacationers should be forced to get away from. They don't want to. The internet at the very least is a superb source of information on the places visited. Regent clearly had contracted Wifi out to a vendor -- the generic screens kept telling us that our room was being billed when the Wifi was free. Wifi is important enough that the technology (not just the tech person on board) should be done by Regent employees.
Entertainment: We went to many of the shows in the Constellation Theatre. They were OK in what they did, but sparsely attended. Something is amiss, given the expenses involved. Regent (and other cruise lines) should look at this old model - Las Vegas lounge acts circa 1960. Maybe it needs changing. Maybe a one act play? A chamber orchestra? Ethnic music from the local region? One can envision these being supplied not by a resident company but by groups based at popular cruise ship stops. Just an idea.
Shore excursions: These depended on the guide. Most were good. But Regent should check out the guides for us in advance. Many people we talked to agreed with us that some stops (on most islands) were uninteresting as they are vacation spots. And there should not be stops at designated shopping centers. Free time in the town, yes; stopping at the diamond or porcelain factory, no. This is insulting to the high-end passengers on the high-end Regent ships. We are more sophisticated consumers than this. It raises suspicions of the motivations of the guides - are they there to inform us or sell to us?
Superb in every way. Spacious interior, balcony and bathroom. Quiet, even in rough seas. Nicely appointed. Many sockets for digital appliance charging.
