I'm signed up for the Sept. 30th start date of this tour, and considering add a day or more at the end because I have a particular interest in Cézanne.
I'm interested in hearing from people who have taken this tour to see if anybody has done a Cézanne focused tour after the RS tour, or if they felt the RS tour included enough info to suit them. I've found one possibility to consider:
