I'm Canadian so things are a little trickier as far as getting seasonal employment in the USA.

My mom has a place in Florida, not too far from WDW and she stays there 6 months out of the year just as snowbird. I'd like to do the same thing when I retire -- get a nice place in Florida to spend the winters, only I'd also like to get a seasonal job at WDW just for fun. I wonder if they sponsor Canadians to work there on a seasonal basis, or if they only hire US citizens...
