Disney raises prices every year and it has never been a cheap vacation.
There has been a lot of inflation all over the world (not just Disney World) in the past year and Disney prices are just another log on the fire.
If your budget is tight, or even if it isn't, you don't have to spend a penny on
Genie+, lightning lanes, after-hours parties, dessert parties or deluxe resorts. And you can have a great time! It is also much easier to leave at parks close without a giant bag of expensive stuffed toys.
As for changes, a lot has changed for sure. There is a lot of new stuff to see if you haven't been in a few years. New fireworks shows, new attractions, new areas. Plus more stuff is returning as they scale up staffing.
There is a large cesspool of negativity out there on many fronts, but you don't have to swim in it.
If you are happy about going on vacation, you will have fun.
One of the saddest things I see in the parks are people stressed-out, overtired and miserable because they "must have fun and do everything" or they spent big bucks for a "perfect trip," and then a ride is down and all hell breaks loose.
Don't go to that place!
