How was your experience?
The 4:30 1 hour trip was a good choice--although we did not depart until 4:45 and returned at 6:00. It was still daylight and we could watch the changing light as the sun went down and observe the houses being transformed as their festive lights sporadically went on after dusk. When finally dark, we could experience the total contrast of how the channels had appeared earlier as we moved along the different shores. The best part was that the boat was NOT crowded.. and after the disembark it was the perfect time to watch the actual boat parade.
