We have 7 days to travel next April during school spring break, and we would like to go to Europe traveling with kids ages 8, 12 and 16. We prefer half day major sight seeing at the most and spend the rest of the day roaming around or hotel down time. I looked at the train ride times but it seems quite far to travel for a 7 day trip. Maybe by air would be better? I would like some suggestions on how to get to Germany from Paris and where to visit in Germany. And also if the combination is a good idea. The other consideration is to go to the french countryside instead of Germany. Any input would be appreciated!
