I suppose it would be a cop out to say something hokey like "the best vacation destination is the one where I get time with my family," eh? OK, fine.
As an homage to my East Coast roots, I have to say PEI is the best family vacation destination in Canada. Sun, fun and really cool red dirt for building sand castles. What more could you ask for?
Blue Mountain in the summertime with its proximity to Wasaga, nice restaurants, kid's programs, on-resort babysitters and comfy, family-friendly condos - all for a super reasonable price - is a pretty close second.
