Actually, I'll be traveling with a 12 year old, a 16 year old and an 18 year old. I've read the guidebooks, and browsed the forums, but I'd like to hear specific do's and don'ts. We'll be arriving late (6:00-7:00pm) on a Friday night, and will stay the week-end. In addition to Sat. and Sun. suggestions, what 1 thing could we do on Friday night? We will be in Toronto in early July.
