OK, next Saturday I leave for my first trip to Europe (5 days). This is a business trip so I will not have a lot of time to sightsee. In London for three days, just a day-and-a-half for fun...the other day-and-a-half for work. Then France for two days, near Lyon. On the return trip, we connect in Paris and have three hours before we leave for the US.

So, if you had just a day-and-a-half in London to play, what would you do? What would you see?

Any ideas or suggestions?
