For those that are interested:
1. I booked through the Canadian site in August 2011 for a trip in August 2012 with
free dining.
2. I then went to Disney on a previously-booked trip in September 2011.
3. While I was there, I went to both the check-in desk and the concierge desk to "verify" the details of my August 2012 trip. They asked me if there was a problem because it looked fine. I told them that I booked it on the Canadian site and was worried that I might be asked for a passport when I returned next year.
4. I was told by the CM that he has "never asked for a Canadian passport" and that the system showed I had a vacation booked with free dining. I was told the same thing at the concierge desk.
5. I wrote down their names and am looking forward to my August 2012 vacation with free dining.
Just sharing my story, no comments on morality please.
