There's a difference between "immersion" and "stupidity":
"As we pointed out last week, Star Wars: Galaxy’s Edge is the only land at Disneyland which doesn’t have entry signage. You see guests with maps trying to find the land and we are told that next to “Where’s the nearest bathroom,” “How do I get to Star Wars Land” is the next most asked thing of most Security and Custodial cast members."
"There are many doors to empty spaces in Star Wars land. Since most of the land requires a bit of trial and error to figure out which doors reveal hidden shops (such as Dok-Ondar’s or the Droid Depot) and which are dead ends, some doors now have trash cans in front of them so guests won’t be so confused.

If you're paying customers don't know where your new ride is or what doors open, you're failing theme park 101.
This sounds very similar to the early days of DAK, where the designers wanted to encourage guests to slow down, get off the beaten path, and look for the details and animal exhibits along the way. In an effort to make it feel more real, they intentionally avoided the traditional subliminal indicators of where the main destinations were. Instead of guests finding surprise discoveries scattered around, they got frustrated by the backtracking, dead ends, and aimless wandering.
And how did it work out? They had to go back and add tons of wayfinding signage all over the park. These signs go beyond the occasional discreet placard pointing the way to another land, and instead have prominent signage for specific attractions, restrooms, and restaurants throughout the park.
Because they were added due to guest complaints after the fact, they intentionally stand out from their surroundings, rather than blend in an area-appropriate way. In a park known for its wide variety of shapes, textures, and colors, these same red rectangular signs were added indiscriminately throughout the various lands. Ironically, perhaps more than any intentional design feature, these signs are the repeating element that ties the entire park together
There's even a pair of oversized toucans pointing the way to the park exit, which is invisible behind the lush Oasis exhibits. Most theme parks are like casinos, trying to keep visitors in place for as long as possible, but this one has neon-colored signs pointing the way out. (For what it's worth, I believe these were actually part of the original design)
When they added Pandora a couple years ago, once again the designers tried to outsmart themselves, and created a twisting network of paths with no clear destination. Even the attraction entrances were designed without mentioning the name of the attraction itself, just signs indicating standby and FP. But within weeks, the operations team had to add "temporary" mobile signs scattered around the land, directing the way to common destinations. Years later, these "temporary" signs are still in place, with no permanent solution in sight.
The only other location I can think of with similar signage is in TDS's Lost River Delta, on the path between Port Discovery and the Indiana Jones entrance. Unlike these intentionally-confusing layouts, that's just a linear corridor of about 200 yards with no meaningful structures along the way, only a small meet & greet that was added a few years after park opening. Instead of trying to make order out of chaos, the signs there are simply intended to reassure guests that the wide-but-meandering pathway continues on to the rest of the park.
The false doorways and alien text in Galaxy's Edge take this all a step further, purposefully introducing elements that (at best) have no meaning to park guests or (at worst) are intentionally misleading. These are the types of flaws that annoy me the most from WDI, because they aren't due to financial, technical, or physical constraints: they're entirely based on the design team trying too hard to be clever and not understanding how their product fundamentally works. Yes, they should keep pushing the limits of what we expect to find in a theme park, but they still need to make it a user-friendly experience. In so many ways in recent years, they've proven repeatedly that they just don't know how these places operate on a daily basis.
