When I talked to the AKL itinerary planner about the PS for our November stay, we also talked about my room requests. I explained that we hadn't reserved concierge for our stay last December because of the possibility of a 'pool' view and that I'd upgraded at check-in - after confirming that we would be in savannah-view. He explained that there are only 6 concierge pool-view rooms and that they are 'smoking-optional' (as if there are smoking-REQUIRED rooms) and since we have non-smoking due to my allergies, that wouldn't be a problem anyway.
BTW, by waiting to upgrade to concierge at check-in, we weren't able to get SS last year, not even on a wait-list, as they were SO booked. This was early December, a slow season. This is one of the reasons we're back again this year - besides the fact we LOVED AKL last time.
