Discussions regarding where people can smoke can be handled in the hotel/destination/rental car forums.
Are we going to add forums for every personal vice? if you want a forum for smokers, why aren't you also asking for a "places in <city> where I can drink tequila" forum? There's as much need for a separate, non-location-specific tequila forum as there is for a non-location-specific smoking forum.
