We wanted to experience Paris so we did the pre-extension. Wonderful adventures daily: Montemarte, Sacre Cour, and all of the typical tourist spots…in addition to finding a street food market, and navigating the Metro! City of Lights night tour was a highlight—-a stop at the Opera House was magical as we watched all of the dancers on the front portico.
The Contemporary museum and the Musee de Orsay were fabulous!
A must is the Batobus! Makes seeing multiple areas/tourist sites easy.
