I have 10 days to travel france and germany any suggestion where to start and what to see?

Watertown I'll be traveling late december or early Jan. There will be two if us and we'll be using backpacks. I know two days will be needed for travel, leaving us with 8 days to sight see. Need suggestions for cities to see and how many days might be needed for each city? Any suggestions would be greatly appreciated!

Eagles Nest is close as well. (but about 150 km. apart from each other).
