From MSNBC:
Driving to Canada is another option, since you won’t need a passport for land crossings until at least January 1, 2008. For those lucky enough to live nearby, that means Vancouver, Niagara Falls and other cross-border getaways are as accessible as ever. Better yet, winter is typically the off-season, meaning fewer crowds and better deals.
In Niagara Falls, the Winter Magic Pass provides admission to four local attractions, including the Skylon Tower and Journey Behind the Falls. During the winter, adult passes are just $27.69 Canadian, plus tax. At nearby Great Wolf Lodge, Winter Magic packages (starting at $259 per night Canadian, plus tax) combine accommodations, two Winter Magic Passes, and entrance to the resort’s massive (103,000 square feet!) indoor waterpark.
