yes, I particularly enjoyed your Dolomites articles having been to Canazei myself, and skied most of the sectors you described.
Without a car I didn’t go to San Pellegrino. I noticed that the maybe similar Passo Costalunga (which is on the local map hence presumably the Val di Ffassa local pass) was do-able by ski bus from Pozza di Fasso, but the connections from Canazei made it not worth attempting.
Nor did I get up Marmolada; the queue for that chair above Arabba put me off. I did go there again one lunchtime and sampled the first blue along the way. How close to Arabba on the way back is your photo of the crowded, soft, mogul slope? I can think of two candidates.
One thing that really struck me about the area was the number of restaurants, cafes and refuggios: even that little gem Ciampedie has three (or was it four?)!
