There are two "Ladies of the Lake". We got the slow one and spent an eight hour day on a 14 knot boat. The trip up lake is marvelous with mountain and forest scenery that Switzerland can't touch. The trip down lake was a drag was a drag in that it was the same thing we had already seen and we got to endure a family of about 10; mostly rude children and a loud mouthed grandmother right out of Honey BooBoo. Unfortunately the crew was in the cabin and at the snack bar instead of taking charge and telling them to shut the hell up. A good alternative to the four hour long down lake trip would be to take the boat up lake to see nature's beauty and the float plane down lake to avoid hours of redundancy.
