I've seen Tokyo Dreamlights several times. And there is absolutely no way any American Disney theme park will ever get anything close to it. Dreamlights is way too expensive to develop, too expensive to build, to expensive to staff, and too expensive to maintain for any American theme park owned and operated by the Walt Disney Company. Just don't even think about it.
And Tokyo's operation will outclass and outspend the American parks every time. And you should see how the front line hourly Tokyo CM's outclass and outperform their lazy and slobby American CM peers.
Just keep spending your money on repeat trips to WDW or Disneyland, and don't worry about how Tokyo does things or if TDO or TDA could raise the bar on their operation to even get close to a Tokyo level of experience. Just keep spending that money and sending those profits to Burbank, please.
