We sailed on the Carnival Miracle in April out of NYC. We had cruised on Carnival's Inspiration 8 years ago(our first cruise) and everything was exceptional. However, we were truly disappointed with this cruise.
Our major complaint is with the difference in the treatment received by the staff. Primarily with their security staff on trying to get off the ship at the ports was the worst. After being at sea for 2 days our first stop was Puerto Rico and I think most everyone was anxious to get off. The ship only had one exit available and it seemed like chaos getting people lined up and took forever. It was not a pleasant experience and the security staff in charge were rude. Same thing happened at Turks and Caicos. We had booked a private excursion at Turks and thought we would miss it. Luckily they waited for us. At St. Thomas it was better because they did have 2 exits open. Not sure why they would only have had one at the others but it sure was poor planning and you felt like a criminal the way you were yelled at by the staff to stay in line etc.
Another major difference we found was with Room Service. On our first cruise I was amazed at their prompt efficient service. Not this time. After the first 3 days I gave up and never called them again. Our order in the morning only consisted of two pots of tea and fruit. Never got that right. It was just the two of us and we just each wanted a pot of tea that basically give us two cups each to drink. We would get one pot of tea and four cups, one pot of tea and one cup, couldn't make them understand. They also would take forever to answer and you were placed on hold or even hung up on. So I gave up and would wonder down and carry it up myself. So they lost out on their tips that way. I also tried putting out the card on the door, but that never came at all.
No problems with an obstructed balcony, Would book again.
