We chose Regent primarily because we wanted to try an all-inclusive cruise to see if they are worth the price and Regent got great reviews. Overall, we loved the boat and the crew. Service was generally off the chain good, but I wouldn't spring for a penthouse just to get a butler. Ours was wonderful, but really didn't do much that a good steward wouldn't have done. We just aren't that needy as travelers, but if you are, it might be a good spend.
Getting on and off the boat was handled exceptionally well in our view. Not just at embark/disembark, but shore excursions. Literally, hundreds of people were moved smoothly and comfortably every morning. They were even handicapped that most of our ports were tendered, not docked, and the crew made it look easy.
Food on the boat was generally good, but not as good as I expected, based on other reviews. I frequently found both fish and steaks over cooked. Other dishes like pasta and risotto leaned toward salty and over seasoned. There were certainly exceptions where fare exceeded all expectations. The French based Chartreuse was our favorite - we ate there twice on the trip and food was properly cooked and seasoned both times. Next, was the main dining Compass Rose, where the chef's specialty menu was usually the best. Especially, good were oxtail soup and herb crusted lamb rack. At the restaurant bottom for us, was the Prime 7 steak house. My medium rare filet was a hockey puck - over done, under seasoned, tough and dry. I do much better at home. The wife's halibut was likewise over and dry. This is not upscale dining.
As I mentioned, we had a penthouse and it was huge! Closet so big the wife couldn't even touch the sides. She lost the shower in bathroom it was so spacious! It was great, but really was excessive for our needs. I think a balcony room would have served our needs fine. Still, if you like space and and service, you won't do any better on any line.
Beautiful island and good overview.
Amazing art and architecture. A must do in Corfu.
Biggest surprise of the trip. MTN is the greatest blend of old and new! Budva has some of the clearest water I've ever seen.
Interesting town and history. Worth doing. Had the best guide.
