Where are some good places to go in Koblenz if there is bad weather? Museums, monument tours, cafe's, connected stores ... any good ideas. I have visited Koblenz in the summer and fell in love with the town. I also know what to expect as far as walking - will return to Koblenz the first week of December with a person who does not like to take long walks. The tickets I'm purchasing are not exchangeable, they must be used on the train originally booked. We will be in Koblenz approximately from 11 AM to about 18:00. Ideally it will be cold, maybe a bit cloudy, but perfectly great and walkable (Plan A) ... however in the event it's rainy and windy, I need Plan B. So if the weather is horrible - what are some good suggestions on what to do from 11 to 18:00?
