Finally, I can offer some advice back!
We are Canadians and just purchased resale WKORV 2br OV - EY. We are in the process of closing.
The process is somewhat more complicated than a US Citizen, but not alltogether imossible or unweildy.
We used a well known timeshare closing company, just as with anything, you need to watch the documents closely, there were several mistakes, but I like to think that has nothing to do with us being Canadian. (Some wording is different, like where your notary signs, etc - so watch carefully.)
The most complicated part (in which we are stuck now) seems to be that a Canadian notary's signature must be 'authenticated' by your local US Consulate. The Canadian Notary must also be 'on file' with the local consulate - so double check that, as we had to phone around to find one that was.
Hopefully there is a consulate nearby - you can appear in person (with an appointment) or mail your docs in and wait patiently. The other option I was 'told' about is to hop across the border and appear before a US notary and skip the authentication process all together - everyone should seek their own advice, because I am not sure if this is possible or of it would be accepted.
Anyway, in our case the consulate is 5 hours away, so we elected to mail it in. Like I say, we are sitting on the Consulate's desk at this time so that is where my advice ends.
Anyone else have any more to add?

P.S.: Yes, the CDN $$ makes it very favourable, I just wish it would sneak back above par - just for a day or two.
