I was on the same French River cruise as Pauline last July and missed quite a bit of the commentary provided due to slow walkers. I often went ahead on my own because our local guides had to wait for all to catch up. I knew this would happen ahead of time and it did not make my trip any less enjoyable. With our limited time in the towns and villages I want to see as much as possible and thus missed most of our guides commentary. The Whispers are great but I was not always with 30-50 feet.
