At that point your only partner for communications will be the agent with whom the cruise is now booked, and the cruiseline will only talk with him.

My most recent example of this happened just last week when I called the cruiseline to confirm that the OTA, to whom I had transferred the booking, had transferred my final payment in time. First the CSR said she couldn't give me that information. After insisting that I just wanted a "yes" or "no" answer as to whether my reservation was paid in full, she said "yes". Since I am working with this agency for the first time (and they had quoted me a exceptionally good price), I just wanted to be doubly sure that everything was done as promised. But, it was like "pulling teeth" to get that simple "yes".
