I had an opportunity to visit the "Rhapsody" in late 2004. She's a late 1970s ship but I was positively surprised by the excellent shape she was in back then. The ship was very clean and well maintained. I understand it does suffer from vibration while underway, but I cannot confirm this, as I was onboard during a port stay only.
Fellow CC moderator Stephan Giesen took a lot of pictures back then, which you can see here:
