I'll add a little to the previous reply, as I've done very recent research. After the world cruise is complete (in, I believe May), smoking is permitted on balconies, on parts of the outside deck, in the Observatory Lounge, and in the Lido Lounge.
Currently No smoking in restaurants or cabins. Smoking areas are available around the ship. Smoking is only permitted on deck in UK ports. Like all cruise companies this is a subject always under review after the fire last year on a cruise ship directly caused by someone discarding a cigarette.
And now I'll add a little more, as my booking confirmation has just arrived. Despite Olsen's website firmly asserting that smoking is permitted on balconies, according to my confirmation it is not.
I am unamused; up to date brochure/website errata and updates are supposed, under Trading Standards law, to be advised at the time of booking. Not once a deposit has been paid, and a booking confirmed.
Smoking should be banned in all enclosed areas. I thought Fred Olsen had banned it at last. I went Balmoral in June, and the experience was fantastic apart from the fug of smoke in some of the bars we particularly wanted to frequent. I have stopped cruising on some lines due to smokers spoiling the cruise by allowing these addicts to pollute everything.
Just come back from a cruise on balmarol. you can smoke outside on deck 7 starbard side and deck 11 but not poolside, inside in lido lounge and conservatory.
