We finally got the air conditioning in the Dolphin Deck cabin fixed after complaining to ships customer service, officers, and finally by email to Stein Crus, the HAL CEO. While they were apologetic, and compensated us the equivalent of 1.5 days of travel, nevertheless, there were other uncorrected problems. The maintenance activities went on at 1:00 AM in the morning with staff coming and going through a doorway opposite our cabin and hammering and banging at odd nighttime hours. The AC went out again a day or two more intermittantly.
The ports we went to were mostly commercial container ports, and buses to get off the docks were not free.
The Lido Restaurant hot food was not kept thermally hot and the cold food served at the Lido Pool was not kept cold. This was after warning us that this was not sanitary, and should be avoided off the ship. By the 25th day we succumbed to problems, due to the passengers coughing into our faces or onto our food. The sneeze shields were not low enough. Passenger handling of food at the self-serve counters was also unsanitary. People would pick up items with their hands, then change their mind and put them back into the serving dish.
Cabins on the sea side of the Dolphin deck were adequate in size, but too noisy and hot. Hallway was noisy at night with the coming and going of maintenance crew that came on shift at 1:00 AM, including moving of carts across loose thresholds in the hallway, between ships compartments.
