You are underestimating the Asian guest and their love of characters and queues.
Less characters might swing someone to do something else with their time, but if they know there are more they could be more likely to focus only on the characters.
I’m happy with the look of this ship so far, I’m glad it’s different. I don’t see the appeal of going on ships that are essentially the same and have the same offerings.
I’m really excited to experience it for myself.
