My wife and I chose the cruise as it was going to Japan where we had never been. We were never advised by Royal Caribbean or the travel agent that the cruise would be mainly occupied by the Chinese. I have nothing against Chinese but when it came to dining they occupied all the tables and chairs in the Buffet restaurant. After they finished their meals they would not leave the table but would sit talking and playing games on their phones.
They put out an announcement for people to vacate thr tables after their meals so that others could sit down, but they did this in english and not Manderin. When I complained to the catering manager only then did they start making announcements in Mandarin, it didn't make any difference.
It is the worst experience my wife and I have had on a cruise. When we booked the cruise no one advised us that the cruise would be occupied with mainly people from china. I understand that there was only about 400 westerners and over 3,000 chinese on board.
Cabin was excellant.
