Royal Caribbean International will join its sister-brand Celebrity Cruises and a number of other cruise lines in returning to Alaska this July. After news that the Senate had passed a measure that would allow U.S.-based cruise ships to sail to Alaska and bypass Transport Canada’s ban, Royal Caribbean on Friday announced that it would start sailing beginning on July 19 with Serenade of the Seas out of Seattle. Serenade will sail a series of sailings with stops in Juneau, Sitka, Ketchikan, Icy Strait Point, Endicott Arm, and Dawes Glacier. Serenade will then be joined by Ovation of the Seas starting on August 13, also from Seattle. That ship will sail an itinerary that includes stops at Glacier National park, Juneau, and Skagway. Both ships are available
