Not to restart a long discussion here, but it must be remembered that ADA and similar laws do not give "protection" to anybody. They merely require "reasonable accomodation" of certain conditions, IF such can be done without undue burden on others or on on entities such as employers and providers of public accomodation (cruise ships and hotels). "Reasonable accomodation" of smokers on ships would probably merely involve confining smoking to the inside of designated smoking cabins, with no smoking in any public area. The problem with Regent's new policy (and that of many other "tag alongs") is twofold. First, they fail to "reasonably accomodate" smokers with designated, non-public enclosed smoking areas (such as a guests own room). Second, they continue to allow smoking in public areas. Most notable is the casino. Some lines didn't give advance notice as Regent correctly did, and just invoked similar policies without notice. On those lines, the casinos have turned into "smoke holes", and that is no good either.
