Check your cabin for charcole from the aircon......

[jaydonny]

Just on our second week on ov1, had problems with the aircon for a week now with wakeing up to spots of black charcole on the bedding in my cabin and my mothers and i heard about some whare else on another deck, i got a bad chest i dont know if its the charcole or a cold they are going to take down the whole ceiling tmorrow when we are in Dubrovnik so will keep you up to date soon.

but i would double check your cabins before you sail for the firt night and pull back the top bed spread so that it shows up on the white bedding......
