Thanks to everyone who provided feedback. From other posts in various online groups, it sounds like there are multiple people who have booked what we did. Sounds like there is even confusion in the RCCL call center on the policy. According to a post on a FB group, rumor is RCCL is investigating the option for anyone getting on in Hawaii and wanting to continue on the 7-day Alaska cruise to get off one stop early in Victoria, BC instead of Seattle to make the cruise "legal". Yeah, I know it's a hail mary - but fingers crossed.
