While I hate to admit it, we had the worst possible odiferous room at our beloved Polynesian. It was two years ago when concierge was temporarily housed in Tahiti. We were assigned the room location we requested, most westerly room, first floor (it would be the first room as you enter the west side of Tahiti.
This room smelled like a cat's litter box and that is no joke! The stench was terrible! We called maintenance and someone was dispatched immediately to tend to the odor. We left him to his work and, surprisingly, the room smelled a bit better when we returned. By the next a.m., however, the stench had returned--another call, more deionizing--smelled better, but still not great. . .you get the idea. We asked to be moved to a different room--no luck, everything in concierge was booked and we were stuck! It really did tick me off that year though because I paid to be in concierge and there were many, many folks upgraded to the service in order to fill the building (Tahiti is much larger than Hawaii).
We made the best of a pretty bad situation and, in fact, ran into a fellow DISer who inquired as to our room #. When we shared it, we were informed that her family had occupied the room earlier in their stay and demanded a move as well--lucky for her, there was somewhere to move her! She and I commiserated over the litter box room!
All of that said--I have never had a room at Polynesian (or anywhere for that matter) that smelled that horrid! Hopefully, it's been corrected--it was a much more serious situation than a little bit of condensation in the a/c unit--this was definitely something acrid within the walls or floors of the room.
