No, I live in America, but I'm also about five minutes from the border and in the middle of a fairly urban college town with a hell of a lot of bars, clubs, and hotels for people to stay in. February's going to be a fun month lol.
Both ways, I'm guessing. Like I said, even though I'm in America I still live in the closest "fun" town to Whistler and Vancouver. People probably already have their passports so it's just a matter of making it through the inevitably long lines at the border checkpoints.
I never said anyone was attempting infiltrate the borders; by "trying," I meant that it's going to be ridiculously, incredulously difficult to get into Canada simply because people will be flocking en masse to try and at least get a view of Whistler if they're lucky.
