I know the rules may (probably will) change before our cruise in November but would like to understand if we may have a problem based on the rules today. My DH and I are fully vaccinated, and each have had 1 booster. This is completely up to date from a UK perspective, and we cannot get another booster until they this autumn. Our boosters were in December 2021.
By the time we get to our cruise in November, out booster will be well over 270 days old. We are hoping to get another booster in October, but the UK plans for boosters is not confirmed so we may not be able to get one before we need to travel.
Based on my interpretation of the Princess rules we are okay since we have a booster even though it was over 270 days ago. Am I interpreting this correctly or does the booster need to be within 270 days?
