re: Paris for Thanksgiving - side trips?

We stayed in the 6th also on St Germain and it was a fantastic location. The only minor problem was the RER line was being remodeled there which runs east-west down the Seine so that hurt our super easy transportation. Instead of a no change to say the Eiffel tower it was multiple changes. So just an inside tip may look into that as it was a major project.

Its really nice in the big cities to stay somewhere close to an intersection of public transportation lines you can take north south and easy west to get almost anywhere. The bus can work for that too and is very underated especially for short 1 mile trips.
