wow, just reading some of the comments.
To be very blunt,
DCL will not care one bit about the negative comments. They HAVE to follow UK Government regulations and all the Instagram comments will be ignored. DCL are basically opening a new market segment, the older age group who have money and time to cruise who want a different cruise experience. Yes their target market is family friendly but at the same time, there are a huge amount of adults who don't have children but still want the Disney experience. Especially after the harsh restrictions in The UK, I would expect there are many adults who would want to cruise but don't want the typical booze cruise and thats the market Disney are aiming for.
These cruises will sell out, and they will be a very different type of passengers who will be on the ship. Its very clever actually, to give these new to the
Disney Cruise Experience passengers a taste of the ship, and I would expect bookings for the 2022 sailings to increase after these UK sailings.
