Well...the problems started when we tried to embark in Istanbul and were not on the passenger list, despite the fact that my wife's parents, for whom we had paid in the same transaction, were.
Eventually our names were found (on the mysterious "other" list) and we discovered our tiny cabins (with sheets and blankets so worn we would have chucked them out to Vinnies years ago.
Then we tried to order some drinks from a waiter who made Manuel from Fawlty Towers look like the Maitre D from the Waldorf. After three tries he eventually brought my mother in law a scotch and dry, albeit a deconstructed version of the drink with a glass of ice, a nip of scotch in a separate glass, and then (much later) a small can of dry ginger. When I asked for a bottle of wine he looked totally gobsmacked and enquired (in apparent shock): "A whole bottle?" Leaving me to wonder whether he had ever taken a drinks order in his life.
Tired, cramped, unkempt and too small to entertain others. Extremely disappointing.
