1592 went to Waterloo in 2007 and loved it. Great atmosphere, tough competition.
One thing that is a pain and kinda discourages US teams from crossing the border would be passports, when we went you could still drive across w/o them but now u must them for air, land and sea crossings. This tacks on about $100/person that doesnt have a passport and they would have to get them quickly.
Waterloo is a great regional and I'd love to go back. They were especially nice to let us play in the snow since we're from Florida
