I know my travel agent fairly well and I don't believe for a second she would lie about this. There would be absolutely no gain for her to do so.
So I believe she did phone
Disney Cruise Lines and ask for a supervisor, whether she actually talked to a supervisor or a random person would be a matter for conjecture.
I think if we assume that people on this messageboard are fairly honest, that Disney is giving completely different answers to people on almost a daily basis so who knows if it is the truth.
As for a couple of other comments
The same travel agent just returned from a 23 day Mediterranean Cruise. She has done it twice before and said that it was worse this time. At all ports in Spain, Italy and Greece the cruise ship received gunship escorts into port and they were checked in through customs by soldiers with machine guns. She said protests in Barcelona and Athens totally messed with tourist activities as traffic was slowed to gridlock because of them. Yes protests are a regular thing in southern Europe but with forced austerity they are far worse right now than normal.
As for changing 2013 as well, I think it is a totally different animal to start mucking with cruises that have been announced and as we understand at least in the case of the longer Mediterrean cruises have sold fairly well. This is totally different from changing a plan for an unannounced schedule in 2014.
Frankly, I hope the employee at Disney is completely off base and the cruises are announced tomorrow but that is the message we got.
