i don't have kids and i didn't go to centreville. and that's probably why i can give centre island 5 stars.
went there today on the last day of summer (and what a beautiful day) and walked over to the bike rental shop with my family. we grabbed a quadricycle and toured the island.
this four-wheeled, four seater was perfect for the four of us -- me and my brother up front, doing the heavy pedaling, and my parents in back, peddling non-nonchalantly but clearly providing a little.
the views are gorgeous, especially of the toronto skyline and the cn tower popping up cutely wherever you go. there are so many places to just stop, sit down, and eat and drink. and marvel (but bring your own picnic, nothing worth eating on the island).
my dad loved riding past the "clothing optional" beach. he thought that was a much better name than "nude" beach. given the number of bikes parked outside the beach, my mom wondered if it was a nudist colony. but no one wanted to get off our quad and check it out.
finally, i didn't yet mention the frisbee golf and i should -- it looked fantastically fun and i will play next time.
