Great write-up and pictures.
Bit of a coincidence, as I've just got back from the same area - we also planned to ride the Ventoux but didn't get there in the end. We did some of the same Cols as you - D'Ornon, Glandon, Croix de Fer. We also did Madelaine and Alpe D'Huez (but not twice). It was brilliant and I think my favourite was Glandon / Croix de Fer (which is one climb really). We stayed in Bourg D'Oisans and as you say it was just a cyclist's town. Even the chemist had a retro bike in the window.
I won't hijack your thread with pics etc - but I kept a blog if anyone interested (in sig below).
Maybe meet at the Ventoux next year
