Six Flags is also apparently hiring
Two years ago, I was told I was "hired" by Walt Disney World through the International College Program, but then they phoned back after two months and said they overestimated the amount of Canadians they could hire and didn't have any available positions to fill.
When I finish my masters, I think I'm going to be gutsy, move to Florida/California, and apply to theme park jobs. Any advice on applying to full time theme park jobs, particularly involving engineering, would be more than appreciated.
Another thing to look into, which I did, is Professional Internships at Disney. I applied, interviewed, but not picked.
They might have one for you, but if you want a Disney job, just keep at it because their website changes often.
