I know Guest Services are hit and miss in how they react to issues. But they were great the one time we were next door to someone who was smoking on their verandah. I tried to be pleasant about it (I could see him hanging over the rail smoking) and casually asked him if he was aware smoking wasn't permitted on the verandahs anymore (even though it had been a few years that rule had been in place). He started ranting and raving like a lunatic (I later learned he ranted and raved like that all the time especially with his family - really feared for his kids) so I called Guest Services. I heard his phone ring just after I hung up with Guest Services (believe he was arrogant enough to say he had been smoking and would continue to do as he pleased - he wasn't exactly quiet and the walls weren't exactly thick). Later, my stateroom host thanked us for calling in and reporting him (I wouldn't expect the stateroom host to address it because it jeopardizes their tip but could tell the host was not a fan of this man either.) The host said Guest Services had called and told him it wasn't permitted and that he would be charged a $250 cleaning fee and if it happened again where the room had to be deep cleaned again, there would be another fee. It was a two week cruise so Guest Services did call back 3-4 days later to see if we had any other issues with smoking.
