This post is no longer accurate. There are new requirements posted. And as a result it is quite confusing as Enhanced Guideline Voyages dropped several cruises that were previously on it and no one at Princess seems to KNOW if the cruises that were dropped [like the 23 World Cruise] was a mistake or if it is going to be put back on the list! In the meantime no one who is Fully Vaccinated but NOT BOOSTED knows what the hell is going on or what will be required of them in order to sail!!!
