shame on the Norwegian cruise line

We were very excited about this cruise and the stops it was making. That ended quickly when 3 days before we sail we get informed that 1 one of ports is not going to happen by choice of the cruise line. We set sail out of LA for Mexico and only a few hours into the trip the ship turns around to head back to port due to mechanical issues but then turns around again to continue on to our first port. We arrive at our first port where we are told that we will be there for 30 hours so that repairs can be done to the ship. after being there for 22 hours we are informed that we wont be leaving at 3 pm but hopefully at 5 or 6 pm. We are then informed at 6 pm that we are experiencing mechanical difficulties still and hope to leave at 10 pm. For the time we are in port the AC wasn't working with the temp being in the 90's and having 77% humidity made our 40 plus hours there miserable.So finally at 12:40 am our ship gets to leave our first port. At 8 am we are informed that we will not be stopping at our other port and will be heading back to LA. Norwegian offers 50 DOLLARS of on board ship credit per STATEROOM, NOT PER GUEST. Later in the return trip after a lot of complaining at guest services they sent out a letter saying they were going to give a 25% refund on your trip cost and a 25% credit towards your next cruise with them. We pre-bought a picture package for this trip and had to have all our pictures done of us at dinner or find a fake background to have our picture taken in front to fill our package. Im sorry but if we wanted those kind of pictures we could have taken them ourselves. We MISS out on 66% OF OUR TRIP and they feel that 25% is okay. This billion dollar cruise line has the idea for their ship to be in port and have service work done at the cost of their guests. DUE TO THE CONDITION OF THE SHIP AND THE WEATHER CONDITIONS WE DEALT WITH AND ONLY GETTING 1 OF THE 3 STOPS THIS CRUISE LINE SHOULD GIVE FULL REFUNDS TO THEIR GUESTS AND OFFER A DISCOUNT FOR THEIR NEXT CRUISE and hope guests will want to sail with them again. One good point to the trip was that the majority of the staff was very nice and willing to try to make you as comfortable as possible.
