The ultra-luxury line has introduced newly revised seven-night itineraries.(Photo by Seabourn) Ultra-luxury cruise line Seabourn is offering a series of newly revised, seven-day voyages on the 458-passenger Seabourn Odyssey between Juneau, AK, and Vancouver, BC, this summer. The itineraries are unique because they combine calls at marquee ports including Sitka and Ketchikan with such rarely visited spots as the Inian Islands and Alert Bay, a small First Nation village on Cormorant Island in British Columbia's traditional Kwakwaka'wakw territory Each of the newly revised voyages also will include glacier experiences at Glacier Bay, the Hubbard Glacier or Tracy/Endicott Arm and will offer the popular Ventures by Seabourn program of expedition-style experiences, including guided Zodiac and kayak excursions launched directly from the ship, as well as hiking and wildlife viewing. The expedition team will include naturalists, scientists, and wildlife and historical experts; they'll lead adventures ashore, mingle with guests and lecture onboard as part of the Seabourn Conversations program.
