This is a very late report, but I'll add myself to the chorus of approval for the week-long Paris tour I took last year. The tour booked us in the Hotel Duquesne*** in the 7th. They provided a 6-day museum pass (YUGE value!), a Navigo metro pass, and other goodies. I had been to Paris twice before and to Europe many times, all independently, but I wanted this tour to take advantage of quality guides to get more out of what I was seeing and experiencing. I was not disappointed!
Terri was our outstanding tour guide. She personally led the walk of the Latin Quarter and Sainte Chapelle. The tour arranged for first-rate specialty guides for the Louvre and l'Orangerie museums, as well as Montmartre and Versailles.
We took the Metro everywhere except for one morning when a surprise taxi strike clogged the Metro and forced Terri to move quickly to get our group onto a city bus to Montmartre.
Three group dinners were included in the tour and I enjoyed each. I'm no foodie so I can't properly rate the restaurants in the pantheon of Paris cuisine, but I was very pleased nevertheless.
I would consider a similar week-long RS city tour in the future, particularly for Rome.
