I wanted to mention about the videos that Ponant sell to people on the ships of the actual tour you have been on. We have never been tempted to buy one, mainly because they are expensive. The one for this tour was 124 Euros.
Anyway, on the last day, we were given one free. We just watched it. It was two USB drives. The USB would not fit our TV or DVD box, so we had to watch it on our computer. One was a half hour video that we just watched. We haven’t checked the photo one yet. It was very poor and to make things worse, most of the footage was of the tour choices we had not made.
My advice is, only get one if you are really really convinced it’s going to be what you expect.
