I will agree that this shows what Disney can do, but it has also taken far to many years to build. It will be almost 6 years from the time they announced it to the time it opened. In comparison, it took Universal 7 years (from announcement in 2007 to Diagon opening in 2014) to build two highly themed lands with three highly themed rides. Also, cost was just insane. The projected budget was $500 million but with the lengthy construction time, i'm positive they went over that. In comparison, Everest cost roughly $100 million. The entire park costs roughly one billion.
We have all known that Disney can produce great things, but they need to pick up the speed while decreasing costs. I feel like it was a real gutsy move to announce Star Wars Land is opening in 2019. That is only three years after the announcement was made and Disney can never build anything from the ground up that fast.
