Our fourth Seabourn; this one to Australia-New Zealand. (Previously: Norway; then Mediterranean/Adriatic, then Antarctic (Wow), then this one, somewhat less overwhelming than the last.
New ship, the Encore, c. 600 passengers. Substantially larger than the previous class of ships (Odyssey/Sojourn/Quest) which in turn were bigger than the previous ones: Spirit et al.) Yes, there are more passengers and yes you know it when you're on board, yet they've done a nice job of enlarging the scale of the ship without much changing the ambience.
Best: Katy Schott (must be the best cocktail pianist at sea); the main Restaurant --4th level (remarkable to be able to serve all those people so graciously at the level of a great hotel dining room pretty much all at the same time -- while rarely anywhere near a market); stabilizers (smooth ride even when they were saying something about rough water); the various bars; the well appointed cabins and their closets, bathrooms, and terraces; the pleasant, apparently happy, rather well turned out and "mature" guests.
