Sorry, I think my post was confusing. I was comparing 2016 WBTA Barcelona to New York and 2017 EBTA Port Canaveral to Copenhagen.
2016 WBTA most northern port is Sydney, Nova Scotia at 46°8' N.
2017 EBTA most northern port is Copenhagen (55° 41' N), but since the cruise has to go around Jutland, the most northern point it will have to travel by is Skagen, Denmark at 57° 43' N. Even Portland (the first stop in Europe) is at 50° 32' N.
2016 EBTA went to Sydney, Nova Scotia and then continued north to Dublin (53° 21' N), Liverpool (53° 25' N) and will end in Dover (51° 8' N), so all those ports are north of Sydney!
Of course, because of the Gulf Stream bringing the warm water from the Gulf of Mexico to Europe, the climate in Europe is far milder than would be expected that far north.
Actually, the intinerary maps that
www.disneycruiselineblog.com puts together are really great for figuring this out as they show latitudes:

I totally get your point about the price being right for the TA cruises. That is one thing that really draws me to them as well. And the sea days. I just loved all the sea days on the Panama Canal cruise, especially the four we hand in a row. So, having even more bunched together just seems like heaven to me! If Disney would just get its act together and let us know what they are doing in the fall...
