I will be booking the closest cabin to the Connoisseur Club, lol. Actually my quit date to totally quit was the end of this year (I have cut down quite a bit) so this really doesn't bother me much.
I don't think this policy is all that much different than what it is now, with the exception of cabins and balconies so I don't think it will draw non-smokers who have stayed away because of the current policy. Smoking is still permitted nearly everywhere that it is now, in the public rooms.
I haven't seen anyone smoking in Compass Rose in ages.
Editing to add, the start of this new policy is in effect the day after LAMB ;)
