I'm looking for ideas to go for 3-4 days in Canada or the US in early August. I'll be visiting a relative in western Canada and going from there. We've already visited places in BC and Alberta many times so looking further afield. I've briefly seen Toronto but wouldn't mind going back; my relative has seen more of it. I've also been to Ottawa, Halifax and a bit of the surrounding area, and in the US, have been to Boston and New York. She's seen a bit of Newfoundland as well, though I've not.
I'm not keen to drive there; she might in Canada, not the US, but is 80 now and hiring a car might prove difficult. So city breaks with public transport and places with tours might be better, though driving wouldn't be out of the question for her perhaps in some places - I was wondering about perhaps Charlottetown/PEI. Other thoughts I had were Quebec City, Montreal, Toronto again (perhaps to Niagara as a day trip), San Francisco. Wasn't sure about cities like Washington DC in August, not too keen on heat. I imagined visiting Quebec and Montreal in the winter with lots going on, but we're unlikely to go then really, and I imagine lots to see in summer too.
Thoughts on those? Any where else that would be good? We like historical stuff to visit; natural scenery perhaps, I like city stuff, museums and galleries etc, though less so for her; classical music for use both.
