Disney has a 5-night Canadian cruise that leaves from NY. It has two days at sea, one day at Halifax, Nova Scotia, and one day at Saint John, New Brunswick. But you can always keep checking the DCL website, as they often add new itineraries!
Cool - we live in Saint John... have to try to get to see the ship when it comes in next time... don't imagine I'd take a trip on it just to come home though

September feels so far away - wish we could go sooner but doesn't look like it can happen - oh well...
Question for everyone though - we only have the quick service plan - is it worth it to get the one with 1 table, 1 qs instead? its around $200 more to upgrade but would be fun to do a table/character meal a day...
