My stateroom was changed without my knowledge and consent and it was worse than the one I had reserved. The new stateroom was located next to the front door and had strong vibrations and terrible noise. The stateroom's door kept on continuously banging . In the shower compartment the pipe was clogged, and the water in the faucet almost did not flow. Within three days I asked to fix the pipe and faucet, but customer service manager answered that nothing could be done, and there was no another available stateroom. But it was a lie. The stateroom next to mine was available.
On all my claims, eventually I was offered a room with a significant surcharge. It was just outrageous.
There were also very few sun loungers on the decks. People had to wake up as early as possible to get any.
