We went to Toronto for two days before the cruise and had a private tour.
The following is a summary of our experience:
1. We had the unpleasant surprise of three days of swarming bugs in our cabin. Woke up with them on my face, the bed and pillow and on the wall. Problem was finally solved but left me shaken. Because of the bug issue, we were unable to use our veranda for the entire trip. The door was locked tight and sealed.
Well, we had horrible bugs for the first three days, all over the walls and bed. Woke up with bugs on my face too. HORRIBLE. They were finally able to get them under control but we couldn't go out to enjoy the balcony for the entire trip to keep the bugs down.
