The CDC’s new guidance clarifies how port communities and cruise lines can work to resume cruising. But the cruise industry said the new rules are “unworkable.” Cruise Lines International Association said in a statement the rules are so murky that “no clear path forward or timetable can be discerned.” The trade group known as CLIA is calling on the feds to lift restrictions on cruising this month. But some see the new CDC guidance as a step forward. The agency hasn’t given much indication on how cruising should resume since late last year. Ketchikan Visitors Bureau President and CEO Patti Mackey said there are still a lot of unanswered questions.
