If you are talking about the Viking River Cruises, last year I took my Canon 6D and 24-70 F2.8 and was very pleased with the results both onboard and ashore. Very seldom did I pine for a longer lens. Enjoy yourselves!!!

I traveled to Lyon in the fall of 2017 with a Nikon d5300 and 18-140 zoom. This was more than sufficient for all the pictures I took.

If you have the chance to do land travel in Lyon, be SURE to see the (1) Ancient Theatre of Fourvière, a Roman theater, (2) the Basillica of Notre Dame, and (3) Museum of Gallo-Roman Civilization, all located within very close walking distance to each other on Fourvière Hill. If you can only see one, be sure to see the Ancient Theatre - it is amazing, and offers some great photo opportunities. You can get to this location by taking the funicular from the Vieux Lyon metro station. Well worth the time if you like ancient Roman history.

something with a 18 / 300 would cover all .

Dump the G10.
Get the 100 - 400mm to replace the SX 50 and the 70-200mm. Small flash and you are good to go. This way you maintain the image quality for all your shots with 2 lenses and a body with a small flash and not carrying 3 cameras and 2 lenses to try to cover the situations that will all be jammed together.

After a number of such trips to the areas that you mentioned, I found that the most practical suggestion is to take a single camera with a lens that goes from wide-angle (say, at least 24 MM) to something like 500 MM. The idea is to enjoy the trip. I have not used the SX50, but from what I have read it would appear to fit the bill. There may be several other cameras made by Sony, Nikon, etc. that are equally good. In my own case, the best trip was with in Nikon 500 and a Tamron 16-300 MM lens (effectively 24-450 MM). You do not want to be lugging the weight of all the equipment that you have listed, and you probably won't have time on sightseeing excursions to be continually changing lenses. If you try that, the other tour members are likely to get quite annoyed that you are holding them up. If you do want a backup, take a pocket-sized point-and-shoot; I had one made by Panasonic that went from 24-600 MM. It produced perfectly adequate pictures when I used it (but admittedly, my standards are a bit short of Ansell Adam's). Have fun, eat a lot of really good food, and enjoy yourself. Best wishes.

Just got back from the same cruise. I’ve done these before and took a lot of gear much of which I didn’t use. This trip I took my Sony a6000 my 18-105 F4 and a strobe for evenings on the boat and found it met all my needs.

Go light and minimalist and possible unless you need certain gear for a paid job. With lots of gear you will soon be ready to toss it in the garbage. You will miss shots and have a sore back.

Couldn’t have said it better myself. On a recent 10 day trip to France, I took one camera and one lens. I saw quite a few “pack mules”—and none of them looked happy.

My suggestion would be take the 6D and the two lenses. If it is not a lot of extra weight or size, I would also include the SX50. But you probably will not need a lot of reach past the 200mm if it will save weight and size.

I wouldn't take so much stuff on a river cruise, or any cruise, just take the SX50 and some spare batteries.
