Why doesn't Royal Caribbean go to Glacier Bay?

Royal Caribbean does not currently go to Glacier Bay National Park because Glacier Bay has a strict permit system that limits cruise ships to just two per day, and those permits are historically allocated to cruise lines with long history in Alaska, primarily Princess Cruises and Holland America Line, which have grandfathered permits. The National Park Service in Glacier Bay manages access to protect its pristine wilderness, limiting large cruise ships to 2 per day, 184 entries per summer season, with permits awarded based on history, environmental compliance, and interpretive programs. Princess and Holland America have been sailing Alaska since the 1970s and have built strong relationships with the Park Service, including bringing rangers on board and funding research. Royal Caribbean, which focuses more on Caribbean and larger mega-ships, has chosen to focus its Alaska itineraries on other spectacular glacier areas where permits are easier to obtain, such as Hubbard Glacier, Dawes Glacier in Endicott Arm, and College Fjord. Royal Caribbean's Alaska cruises from Seattle and Vancouver still offer excellent glacier viewing at those locations, with itineraries that include Hubbard Glacier which is actually larger than many Glacier Bay glaciers. Additionally, Royal Caribbean's largest ships are too large for some narrow passages in Glacier Bay and are better suited to ports like Juneau, Skagway, and Ketchikan. So it is not that Royal Caribbean is banned, but that Princess and Holland America hold the limited Glacier Bay permits.

Royal Caribbean does not currently sail into Glacier Bay National Park because of a highly restricted permit system that limits access to just two large cruise ships per day, and those permits are historically held by Princess Cruises and Holland America Line. Glacier Bay National Park is a UNESCO World Heritage Site and one of the most protected parks in America, and the National Park Service strictly limits cruise ship entries to 184 per summer season to protect wildlife, water quality, and wilderness character. Permits are awarded based on long history in Alaska, environmental record, and educational programs. Princess and Holland America have been sailing Alaska since the 1960s and 1970s and have invested heavily in Glacier Bay, including bringing National Park Service rangers on board for all-day narration, funding research, and operating with cleaner emissions. Royal Caribbean, which operates larger mega-ships focused on Caribbean and global itineraries, has chosen to focus its Alaska program on other spectacular glacier destinations that do not require Glacier Bay permits, such as Hubbard Glacier, which is actually the largest tidewater glacier in North America, Dawes Glacier in Endicott Arm, and College Fjord which has eight glaciers in one fjord. Royal Caribbean's Alaska cruises from Seattle and Vancouver still offer excellent glacier viewing at these locations. Additionally, some Royal Caribbean ships are too large for the narrow channels in Glacier Bay. So it is not a ban, but a limited permit allocation that favors historic Alaska operators.
