If the TA doesn't call, it may be never.
95% or more of TA's are independent contractors working from HOME. The TA just needs a phone. She can do this in her PJs while standing at her kitchen counter and her kids are watching Frozen 2 if she needs to. Hmmm . . . how do I know this? Have you guessed what I do for a living yet?!
They asked the people immediately affected to wait until they received their e-mails because they had to set up their systems to accommodate the 125% (and in some cases 150%) FCC they were receiving for the canceled cruises.
DCL very rarely offers this to guests (usually for cruises that were massively impacted in some way while sailing - hurricane-related, typically), but this was offered en masse and they had to back the taxes and fees out. Guests whose cruises were not canceled can simply call, give their reservation number and cancel or modify their cruise like they have ALWAYS done as that is what their system is already set up to do. As I mentioned, this takes no more the two minutes for a DCL phone CM to do.
