This was a great experience overall; you get on at the marina, and go up the canal through the Miraflores double locks and the Pedro Miguel single lock. It is awe inspiring! Jose was our narrator/guide, and was very engaging and entertaining, with lots of interesting facts about the history and process.
The cruise includes coffee, breakfast, and lunch (served at around 10:30). All were mediocre. But...the food isn't the point of this experience so it didn't really bother me.
