Warning to all travellers on Royal Caribbean Cruises, if you want water, buy it at the bars or restaurants @ $3.00 a 600ml bottle, if you consume the water in your stateroom, they will charge you US$7.90 600ml bottle. We were charged US$15.80.
For us Aussies, that converts to AU$10 per small lbottle FOR WATER.
There is no sign or warning to passengers what it costs for water left in the stateroom, it is definitely not complimentary.
