Hi Mike,
Being a leper and living on the island I can attest to the fact that most hotels have strict no smoking policies in communal indoor areas. You can smoke outdoors and in your bedrooms as long as they are smoking rooms. In bars and restaurants under a certain amount of M2 the owners can either be smoking or non smoking and there will be a sign on a window or door to let you know. Most big venues have a smoking and non smoking area.
Common sense prevails and the non smokers can have a night out without coming home stinking of smoke and us smokers can light up without the tutting and filthy looks.
