The Suite Life of Zack and Cody was one of my favorite shows. It was about two twin boys who lived in a hotel with their mom, who worked there as a singer. The twins made friends with all of the employees at the hotel. They were always up to something mischievous. The show had some good humor and interesting story lines, but the last few seasons held a huge change. The twins and their friends moved to a cruise ship. Which changed the name to The Suite Life on Deck. They no longer lived in the hotel. Zack and Cody are all grown up and lived and went to school on a ship without their mom. They have new friends and new employees, almost a completly new cast.
After this major change of location and cast, the show was never the same. The innocence of the twins and their shananagians was gone. They're in high school now and their humor just seems more forced and less funny then it was when they were just two twelve year olds living in a hotel.
