Well, I've been chasing for a response for several weeks now and just getting holding replies. Eventually yesterday I received pretty much what cwdefouw predicted:
What I'd asked for, repeatedly, was a full breakdown for both cruises showing each individual port charge.
I replied to say this is not an acceptable answer, please provide the detail I've requested. And I copied the e-mail to Karl Holz. I also e-mailed John at DUL asking for his assistance (because he was instrumental in resolving the Panama fee issue in 2008

), who replied straight away and said he has contacted his Disney sales rep about it.
Anyway, when I got home from work today I received a phone call from an "Executive Correspondent" in Karl Holz's office. He tried to explain the situation to me in what I can only describe as a very Disney way - I don't think he intended to give me any information but expected to just placate me. I certainly don't think he was prepared for the conversation which ensued.
In which, interestingly, he did admit that "We do build a little bit in", because the taxes "fluctuate". But he said that 100 days prior to each cruise they refund any difference. However, he also told me that they have checked and there has been "an error in calculation" for 2 of the ports, that this will be updated and the taxes will be "slightly less". I'm not sure if he was referring to the 7-night SC cruise or the 3-night repo.
I explained that what I am seeking is a full breakdown for each cruise to show how the amount charged for government fees and taxes has been reached, per passenger. He tried in several ways to tell me that they dont have the figures, and/or they may change, but I refused to accept this. As I said to him, someone at
DCL has come up with this figure, they must be able to provide a full breakdown. I dont care if it is an estimate or if it does change, I want to know how the figures on my reservations have been reached, ie a dollar amount for each port adding up to the total.
He said no-one has asked before I told him, perhaps not, but Im asking now and I cant see the problem in providing me with the information. I said that I am not saying DCL have got it wrong. I am simply asking to be given full information so that I can understand how these figures have been reached.
He finally agreed that they will provide this breakdown - I asked for it to be sent by e-mail. He said that it isnt that they have refused to provide it, but that they didnt understand what it was I was asking for and he was seeking clarity.
I know there are some differences between American English and British English, but it would seem Disney English is another language altogether!
If I do get the information (call me a cynic, but I'll believe it when I see it) I will, of course, let you know.
