I had a couple vouchers to redeem for a Mariposa cruise/tour. I got the vouchers through Doors Open Toronto having volunteered a bunch of hours back in May 2016.
My dad and I did an afternoon cruise on Labour Day. It was a nice, shortish cruise and was enough time to take in the views, cruise around a part of the islands and return back to the pick up point behind the Harbourfront Centre.
This would be a great cruise for visitors to Toronto. I thought it was interesting and did a learn a couple things from the commentary and missed a couple facts that I had to look up.
