It's still the best experience out there.
Up until this past week, I would have agreed with you. But we just took the children to two smaller, local theme parks, for a tiny fraction of the cost of Disney, and they had
more fun there, than they did at Disney.
Here's the thing: to most young kids, a ride is a ride. And most of the rides at Disney are available anywhere. They're just themed better at Disney, and probably have a better paint job. Now,
I noticed the difference in the details, theming etc... But the kids didn't at all. Instead, they just said, "Oh look! Splash Mountain!" when we came to the Log Flume ride, and were able to ride it three times in a row on a busy summer day, with only a 5-10 minute wait, instead of a 60 minute wait.
Our son outright said he preferred this trip to Disney, and I can see why: they're smaller so it was less walking/less tiring, there were less crowds and waits were minimal -on a very busy summer afternoon, the longest we waited for a popular ride was 30 minutes. Many times we rode rides repeatedly with minimal wait. We were able to do far more rides at these parks than at Disney. Plus, it's quieter and not as much of a sensory overload as Disney is, lots of shade, picnic and sit down areas. And it's a fraction of the price.
I personally missed the parades/shows and fireworks, they didn't seem to at all. Our daughter did miss the Disney character meet and greets, but otherwise also loved the trip.
So... it's funny. I went into the trip worried that Disney had "ruined" us for all other theme parks, and worried the kids would be bored; instead, we found the opposite: our trip to Disney made us appreciate other theme parks even more, and actually really put it into perspective of value. For us, honestly, we've decided Disney isn't worth the cost (right now). Not while they're in such a state of transition/cut-backs. Not when the kids have as much/more fun at other parks. It kinda made me sad in a way, because I still love Disney and I want to go back, but I really can't justify the cost.
So, we'll wait a couple years until the new stuff is built, until the kids are older and more into the "details", until they're older and better able to handle the crowds and waits of Disney, and can do longer days so we get more value for our money.
