"Most allow smoking on balconies & in casino's, all allow it on sections of the outside deckspaces...ie either the port or starboard side."

I can tell you from experience, that Azamara and Oceania have the most restrictive smoking poloicies...

One tiny space in the "nightclub" and one table/area on the ouside pool deck. That's it.

This info is probably helpful for both smokers AND non-smokers.
