This isn't meant to be a review per se, just a few thoughts as someone who just cruised on one of the larger ships (Quest) for the first time. I have been on the Legend, Spirit and Pride many times.
The last time I was on the triplets was 2010 and although we had a nice time I felt it was time to move on and the triplets were feeling too dated, too intimate and too lacking in evening entertainment. We love to dance and we don't care for the small dance floor in the club on the triplets.
We sailed on the Quest on October 20th from Rome to Venice. We had a wonderful time. When we embarked it felt like the usual low-key, smooth, organized Seabourn experience. However once I got on the ship and walked around, I felt I was definitely on a "cruise ship" and not a large yacht...which I think is both negative and positive.
We loved the cabin. On a macro level it wasn't much different from the triplets but the little things mattered - the table where you could really eat dinner for two at etc.
The food was fabulous as always. Chef Thorsten (sp?) was both personable and accomplished. I loved our "shopping with the chef" outing with him. Seabourn laid on a coach for twelve guests and took us to the fish and produce market in Corfu. He bought some olives and dried beans; then two large fresh fish that cost close to $500 each.
The rest of the guests stayed in the market area and we rode back to the ship with him picking his brains on cooking techniques...very helpful! He had a Michelin starred restaurant in Hamburg so clearly he knows what he is talking about I was amazed at the involved process for the consomme, no wonder it tastes so much better than regular old stock!
We had dinner at the Colonnade (Indian food) and low and behold.....a whole roasted tandoori fish.....delicious! Of note, the lovely Chef who took us shopping with the Chef in Gaeta, Italy in 2010 was there...Jez (sp?). What an asset he is to Seabourn, always kind and friendly. We loved our outing with him on the Spirit where we bought tons of cookies and fresh cheeses from local merchants.
The food was really wonderful. I only had one bad dish. For lunch one day I had the linguine carbonara - a huge plate of sticky sauce and thick noodles. OTOH we had wonderful osso bucco in the Colonnade and fabulous steak in main dining room. And oh, that consomme...

I can't say enough about how we enjoyed the entertainment. "The band" yes that was their name, were incredibly talented. Two amazing guitartsts, pianist and sax player and the lead singer Wendy was great. All of them made a point of talking to us and thanking us (they really didn't need to but it was gracious of them) for coming to the club every night and dancing. The cruise director team were very personable too (Heidi, Dan and Tammy). There was also a singer onboard called Stephanie whom we loved too.

The larger ships are a little more impersonal than the sisters, but not by much. A few staff still called us by our name, we got invited to dine with the Captain and another senior officer, it felt like the old Seabourn. There were 193 club members on board and 250 "newbies."

The only negative I can think of is I didn't enjoy "rock the boat" as much as I usually do. The singing was absolutely wonderful but it wasn't as much of an "event" as I remember it doesn't include dinner, rather it's a 90 minute singing and dancing fest. One of my favorite memories is a whole rock the boat evening in Monte Carlo, docked up against downtown with fireworks going off from a local event. We had dinner out there on the deck that night and the staff cleared the decks in a jiffy and turned it into a dance floor. The area for dancing on the Quest, by contrast, is very small.

I'm more inclined to go back on the larger ships in the future but wouldn't rule out the sisters. Sometimes I did miss the intimacy of the triplets. But this cruise turned out to be one of those great cruises where everything came together; people, weather, food, ports.

My favorite moment on the ship? Leaving Dubrovnik, beautiful weather, beautiful sunset, champagne and caviar party, the band playing on the deck, good company at the bar- priceless......
