During our December 7 - 17 visit at PC, people seemed to be using the designated smoking areas. I didn't walk around the entire resort, but the area where we stayed people seemed to be considerate.
We were at the CBR in June and the people who were smoking were very courteous. I saw a couple of people walking around the promenade smoking but, other than that, they stayed near the designated smoking areas.
We stayed at the CSR in September. DH and I often walked the entire resort and 99% of the people were in the designated smoking area (and this includes by the Dig Site Pool as well).
