We've sailed on all the Seabourn ships, from Pride to (now) Encore, with the Odyssey class Sisters in between. We expected to not like the larger Encore, but, honestly, it felt less crowded than the Odyssey-class ships. Very deluxe, much more sophisticated in every regard, with vastly improved food and restaurant venues. The new Thomas Keller Grill is world class, as is the new Sushi Restaurant. Colonnade and Patio Grill offerings are even better.
The Retreat with its private cabana set up is very very nice, with even more attentive service - a hard thing to imagine-- than you get by the pool.
Shore Excursions continue to slightly disappoint. Really don't like the lack of discipline re. tour departures. If people can manage to show up 15 minutes past the scheduled departure time, they should be left behind. Many of the excursions still aren't Seabourn-class...in terms of content/execution, they could be Carnival excursions.
The spa has been reborn: now first rate.
