Disneysea might be a really fresh experience for those who have visited only WDW and DLR. The scenery is amazing in Sea, while the technology is amazing in TDL. TDL is the same as the Magic Kingdom, but with a few exceptions.
-The Audio Animatronics are far more advanced then any other park( For example, Splash Mountain, Pirates, The Haunted Mansion, etc.)
-They have original scenes.(Eg, Haunted Mansion with the library and the popping out faces from portraits)
-Original or Revamped Rides.(Eg, Pooh's Hunny Hunt, Monsters Inc Ride and Go Seek, Cinderella's Fairy Tale Hall, Country Bear Theater, Enchanted tiki Room, etc....)
-The food is delicious.
-Audio Animatronics advanced.
-Scenery is amazing.
-Food is like eating in a expensive restaurant.
-All the lands are original(Mediterrenean Harbor is the Main Street, American Waterfront, Cape Cod, Port Discovery, Lost River Delta, Arabian Coast, Mysterious Island and my favorite, Mermaid Lagoon.)
-Tons of Original Experiences.
