We were on Disney Dream in 5536 October 5-9, and encountered noise for the first time in a category 4E (5036 on Disney Dream and 5536 on Disney Fantasy on previous cruises). The second night of our 4-night cruise, it was from the 10:30 pm of the Nightmare Before Christmas Sing and Scream showing in the Walt Disney Theater. Since there had never been a late night show in the WDW Theater on previous cruises, we chalked this up as a one-time annoyance. However, on the next night, we could clearly hear and feel the soundtrack of the 10:30 pm Guardians of the Galaxy showing in the Buena Vista Theater, which was easily 8 cabins and a bank of elevators aft. We called to complain, but it was on no use, until the next day when they offered to move our cabin for the last night. We chose not to move for one-night, and we did not hear anything that last night as the 10:30 pm was a more docile one. In the future we maybe upgrading to a 4B or 4C on the newer ships to avoid this issue and still have the bigger cabin.
