I know the first thought of many, myself included, is "Well Universal has been charging for quite awhile now.", but then I think, but Disney wants to be the preferred place to go, so having a one-up in Universal in terms of perceived value is kind of a big deal for them. Let's face it...Universal isn't just a day trip anymore. They're seriously looking to steal from WDW's guest list, so to speak, ever since the addition of Wizarding World and Volcano Bay. They now have 2 main parks (Which for some folks work out to be more like three since people tend to to treat the entire Wizarding area as a park of its own.), 1 water park, their answer to Disney Springs, while adding more and more resorts themselves.
I used to see so many people say "We're going to Disney for a week, but taking one day to go to Universal". Now I see a lot more folks splitting that week more evenly between the 2, which 4 days at WDW, and 3 at Universal or something like that. For our next trip,
we're even going to spend 2 nights at a Universal Resort and we have
never done that before. Our current plan is to be at WDW for 7 days, enough for all 4 parks and the 2 water parks. We're NOT currently planning to go to Volcano Bay, however. My kids are getting older and they like some the more intense rides at Universal, plus they love Harry Potter, and since Disney screwed up on that situation

, Universal automatically gets our money to feed our Potter love. But if Disney is going to start acting more like Universal, then people like us, who currently still prefer Disney, may start to have less reasons for that preference. If they start to feel more and more alike, then we start to lose the reason to give more of our money to Disney. It seems so crazy (and sad) to me to think that someday we may treat Disney as the add-on to an Orlando trip.
So, long story short, I think Disney needs to remember that while it may be great for them to use some of the ideas used in Wizarding World over in Galaxy's Edge, people still like them for the the things that makes them different from Universal, too.
