This isn't specifically related to checking in to the muster station, but I received an email from Royal Caribbean before the cruise to report to Guest Services and redeem the old "Dine, Drink, Discover" perk I was grandfathered into (due to multiple Lift & Shifts).
Royal Caribbean had staff stationed at the Guest Services line whose sole purpose was to kick people out of the line. Their job was to shorten the Guest Services line by forwarding people to other places if they could be more efficiently handled there.
Soooo.... Even though my letter said specifically to report to Guest Services, the person kicking guests out of the line thought that I would be better served by the Beverage Sales staff. So I was sent to that line.
As you can probably guess, the Beverage Sales staff had no idea what to do. After consultation, they decided the best place for me to go was to the Dining Sales line. I have no idea the logic they used in coming to that conclusion--other than perhaps to get me out of their hair.
That was a really long line, and once people got to the front, they each took their time scheduling and rescheduling dining times to best fit their plans. Finally, I got to the front of the line and presented the email. His response? (Wait for it.) "You need to go to Guest Services."
So now I am back in the Guest Services line approaching the same person who kicked me out before. I refused to even talk to him and stayed in line. Once I got to the front, all was resolved.
So yes, I am another person who has encountered some particularly annoying Royal issues that simply shouldn't exist.
