800.526.9723 is the number that I call. This number also gets you to the Diamond desk.
I had a crazy and funny experience--I applied for Royal shareholder's benefits on my Odyssey January '26 booking. I wanted the booking to be transferred to my TA. It was denied by the Sales Dept as it was considered a Casino booking. The booking had nothing to do with the Casino as the booking was done on board. So, I call the C&A desk to get clarification/fixed. The agent tells me with certainty that the system has identified it as Caino related. Rather than argue, I asked if the agent could provide me with the direct tele# to the sales dept. I call and I recognized that it was the same person that I spoke to previously. So kiddingly, I said I don't think you are going to be of any help. 🤣 Called the Casino desk and got it resolved. Still did not get a proper answer as to why it became a casino booking.
Bottom line, I did not want to lose $350 in OBC provided by my TA.
