This will probably get some negative comments, but hear me out...
I would love to see another Disney theme park in the US, other than California or Florida. I know this won't solve the Main Street USA fireworks issue, but our family has opted for different vacation experiences the past few years because of the crowds at Walt Disney World and we always went there in off season. There is no place like it on earth, but using apps to beat lines, all the strategies to maximize FastPass+ and still waiting in crowds for just about everything just seem so opposite of Walt's vision.
Yes, he was a savvy businessman. Yes Disneyland was an ingenious way to have marketing synergy with the films. But early on Walt wrote about wanting the place to be "relaxing" and a place where "kids could play." He was heavily influenced by Griffith Park in LA, Tivoli Gardens in Copenhagen, Electric Park in Kansas City. Honestly, I think he would be horrified by the exiting stampede on Main Street USA and would be pushing Roy for another park or two even.
Disney toyed with building Mineral King at Sequoia National Park in the 1960s and more recently Disney's America in Williamsburg, VA. in the 1990s. I wonder if another park would thin out crowds at existing parks a little bit. I've written before that maybe Disney could even create smaller scale, innovative experiences in several locations around the country. This is Disney we're talking about, the Imagineers.
We want to take our son to see the new Galaxy's Edge before he graduates high school, but hearing podcasts say it will be overrun with crowds for the first few years just discourages us from going. It's a big investment for us.
Disney sets the standard in THEME parks. There are plenty of thrill ride amusement parks in the US, but few theme parks. I'd give Busch Gardens, Williamsburg a huge honorable mention with it's Europe themed lands, great rides, smaller crowds, decent shows and beautiful landscaping, but it's no Disney and I always leave there feeling like I wish I could have the crowds of Busch Gardens with the amazing features of Disney. Busch Gardens isn't even a full year park, but they've learned to do off-season Halloween and Christmas events.
Can we at least dream about a new park and enjoying the magic again? In the mean time, for goodness' sake create some other views of the nighttime show, fly some more amazing character drones that can be seen anywhere around the castle, stage some other popular experiences off Main Street each night, pretty up some extra exits.
