Yes fridges are in all cabins. As for the current most popular question about cabin noise, which seems to be asked about every cruise ship at the moment, I have never experienced a noisy cabin on any cruise ship I've been on.
Yes there is either a fridge or some sort of cool-cupboard. As for milk - go up to the Windjammer at in the morning and take a little carton of milk which is by the cereal section. I had an Aft JS and no noise at all. For those in the Aft of deck 8 don't forget the 'secret staircase'. The Secret Staircase is a real find! It is right opposite #8070 and goes from deck 8 up to deck 9 only – ends up in the Solarium. The door gets shut around 11p when the Solarium closes. The Solarium had various foods set up during the day – we would go up first thing [in our robes] to get coffee, juice, Danish pastries and fresh fruit to eat on our balcony – In the afternoon there was a antipasti selection set up – of cold meat, cheeses, olives, sun dried tomatoes and bread – so again we took a selection down to the balcony to drink with our bottle of wine during sailaway. In the late afternoon and during the evening there were burgers and hotdogs set up there.
I forgot to mention, our aft JS was on deck 8 too. And don't forget to sign up to the meet and mingle for this cruise. Well worth it.
We had a fridge on Voyager filled with cans of lemonade etc. However on shore we bought small botles of water and moved the provided cans around to fit our bottles in. Couldn't believe it when we received our statement and they had charged for the cans we had moved (not drunk) We complained and they reinstated our account, explaining that the fridges had some sort of sensors to detect removal and hense the charge. So if you buy milk to put in your fridge, make sure you check your statements.
