2. Turning Grand Avenue into a queue
Guests who experienced Pandora: The World of Avatar during its opening weeks will likely recall when Disney had to use the bridge to this land from Discovery Island as a holding area for guests waiting to get into the popular land when it was at capacity. And while this bridge was a natural area for guests to wait just outside the edge of Pandora, Disney's Hollywood Studios doesn't have a super easy structure like this that is out of the way enough for a massive queue to sit without disrupting other areas of the park. However, Disney has been working on a solution to this issue over the past few months, widening the paved areas of this land, and making it suitable as a holding pen for guests who are waiting to get into Star Wars: Galaxy's Edge.
We know that Disney's Hollywood Studios will not have a ticketed return-time system for this upcoming land (though maybe they should) but due to capacity issues they will need to use a system similar to the one Universal used when The Wizarding World of Harry Potter - Diagon Alley opened, where guests can queue up, and then be let into the land in batches as other guests exit. And right now, it looks like that entire queue is going to take up the majority of the Grand Avenue Area.
3. New sign for Animation Courtyard coming
Though most of the changes coming to the park have to do with the imminent opening of Star Wars: Galaxy's Edge, another weird change coming is the addition of a new sign in front of the animation courtyard, showcasing the characters that are now a big part of the park. This sign was unveiled during the 30th anniversary celebration of Disney's Hollywood Studios, and though we don't know exactly when this new sign will debut, it seems likely that we'll see it sometime this summer.
