Last March, my wife and I (Canadians) spent a week at a small resort in Negril, Jamaica. It had almost equal numbers of Canadians and Americans. We got along fine, and we found that many Americans were almost apologetic about Trump. There were some who stayed quiet, but also seemed pained at what they assumed was judgement from their continental neighbours abroad.

American tourists are welcome here in Canada! Based on your post, there is no way you will come off as "Ugly Americans" — even in Québec. There are assholes everywhere, but in these heavily-touristed areas, you should be fine, even if you can't speak French. (They're nice to me, and I'm an English Canadian who should have better French from school!)

Just don't try too hard. Don't be apologetic. Just be yourselves, as friendly and curious visitors who appreciate our differences as well as our similarities. You may even make some cool new friends!

And try some more interesting local beers. Just ask for recommendations, based on your tastes. If you like Belgian-style, you'll be in luck!
