I tend to take my vacations in September, when most kids have started school. I tend to avoid going anywhere on holiday weekends or school breaks. Prices go down and there are a lot less crowds. Every time I have gone to Vancouver, BC, I have not seen many kids around. BF and I were up in Whistler in mid January, and surprisingly did not see many families. We stayed in a hostel, which was not kid friendly. Also cheaper rates. There were a lot of college kids, but that is different. Just do your research and avoid going on vacation during school breaks. I would like to find pet friendly hotels, though.
