We are trying to plan a family vacation for this summer for our young family (including my husband, myself, and our 4 young children ages 18mos - 7years). We are looking for a destination about 6 hours drive from Toronto, Ontario, Canada. We'd only be spending about 5 days, and would want a variety of activities to keep us busy and also relaxed. We prefer something a little off the beaten track (ie, probably not any major cities, unless there's a special reason). Any suggestions?
