I was in E244 and this was an AFT cabin with a back view from the window. Well, the disappointment began when I realized that this window was probably not cleaned in about several months as there was so much grime on the window that there was very little view at all! This cabin was basically right in the middle of the back end so it added a few extra square feet to the room. To give Carnival credit, they did a nice job with the bathroom remodel but the room itself seemed so basic. Aside from my beds there was only one wooden chair there--not exactly comfortable for sitting---though I knew that I was downgrading when I booked, I expected at least a small stuffed armchair!
Now for me the clincher was this. My cabin was directly across from the stairwell landing that took anyone up to the next deck which was roped off as a crew rest area. From there passengers were able to walk up another flight to the serenity deck then one more to the buffet. The downside was this: the crew rest area was also a designated smoking area! This area covered that little side and all around the top of that deck. Hence, each time the door was opened on that floor, the downdraft took the smoke with it and it was blown right into my room! Damp towels helped that but then because the crew still smoked on the deck above, it got sucked into the AC unit and spread it through the cabin! In order to deal with this I had no other choice but to have an engineer come in and block the AC vent so this mean I was in a room with no AC in over plus 30 C weather--it was either sweat or choke.
Unfortunately, the ship was full so there was no other cabin available for me to move to. Being severely allergic to smoke I then desperately asked if I could just end my cruise early in Key West and then make my way back to Miami from there. I found out that in order to do so would have meant a US gov charge for early departure of $395, plus proof of new hotel bookings to cover the days that I would remain in the USA then proof of purchase of how I would get to my departing flight. With the cost of the internet on the boat, trying to do all of that plus pay those other fees would have more than added up to an extra thousand or more, so I decided to swelter instead.
