Carol, sincere thanks for posting this update in policy.
I will respect your request to refrain from commenting or offering an option on the new RS protocols, other than to say that obviously the RS organization to trying to "strike a balance." There is no "perfect" solution/no "perfect balance." More learning will take place as the world goes forward.
I agree that I wish the CDC would update guidelines to include booster shots, especially as future boosters continue to better targeted toward more currently morphed covid variants.
I do hope the RS organization will continue in 2023 to post its weekly experience with # of tour goers who have had to leave tours due to covid. I like how transparent that has been.
Again, thanks for the heads-up on the changed policies.
Safe, healthy travels to all.
