Silversea runs two quite different operations under one flag, and both are excellent.
The classic fleet is small, all-suite, butler-serviced and almost entirely inclusive — the ships sail the Mediterranean, the Caribbean and the great port cities of the world with a service standard that is genuinely among the best afloat. The expedition fleet takes the same standard to Antarctica, the Arctic, the Galápagos and the Kimberley, with ice-class hulls, Zodiacs and expert naturalists aboard.
For an incentive program, that range is unusual and valuable. You can offer a polished European week or a genuine expedition, and the service, food and feel carry across both. See the at-sea overview for the rest of the brands we represent.
