Not happy

Went on Christmas Cruise to the Caribbean. The ship has not been refitted . The inside cabin on Marella Explorer 2 has got a fridge but it doesn’t work ! It’s stocked with drinks , but they are warm ! When asking about this we were told all inside cabins have non working fridges! Only outside cabins , why! The room smelt because the bathroom has mild in the grouting of the shower , the carpets are not vacuumed around the edges(previous occupants left small pieces of plastic clothes tags around the Ed he s which were still there when we left . The bed is comfortable but the bed base has dust( dust mites ) around the edges of the mattress !! The cleaning staff spend most of there time in the corridor smiling , friendly , but then again it was Christmas (tips)? The market place restuarant was ok although Christmas dinner was poor and found a dirty plate in the warming rack . It seems standards are falling and having paid a lot of money we think it’s more a booze cruise than a classy 5 star ship . Will not recommend lot use TUI again
