When we made our original reservations for June at AKL (savannah view, standard room), we requested non-smoking (guaranteed-asthma), arusha savannah view, highest floor possible.
Later, on learning of the construction, I called back and changed them to non-smoking (guaranteed-asthma), zebra trail, 2nd or 3rd floor.
Then I called back this morning to confirm everything since we leave in a couple of weeks. I asked her to read my requests back to me so I could verify them and all it said was zebra trail, highest floor possible.
Moral of the story, if you've altered your requests, call back later and verify that they actually made the change in their system.
On another note: This was the second ressie on a split-stay for this trip. I noticed that the non-smoking request was eliminated from the system on both of my ressies. I know this must be because all rooms are now non-smoking, but I had hoped the notation would still be there so they would know to not place us in a room that was recently a smoking room. Probably not a big deal, though, since there were so few smoking rooms to begin with, but I thought this was worth noting for anyone with medical issues since it happened to both of my reservations.
