I think this all really just comes down to a difference in personality. Just like planning, there are going to be people overjoyed at putting so much time into planning out the details and making reservations (like myself) and people who hate every second of it. Likewise, there are people who wouldn't dream of visiting the restaurant down the road without reading detailed reviews (also myself) and those who want to go vacations that require as little research as possible. I can completely understand why someone in the latter group would be frustrated trying to plan to Disney and realizing they're probably going to spend a good amount of time reading restaurant reviews and guides on how to maximize your FPs, or, even worse, just booking the trip and only realizing these things are necessary once they get there.
That said though, I stand by my opinion that there has to be some accountability for your own happiness. If you don't want to have know every little thing about the place you're visiting, that's valid. But it's unfair to go to a place that requires a good bit of knowledge about the services offered and how they work and then blame them because you don't want to have to know those things.
In short: if you don't want to have to research your vacation spots, I get it, but the fact is that there are times where that's going to leave you unprepared for the realities of vacationing there and the responsibility for that falls on you.
I completely agree. We have been taking trips to WDW pretty much every year since 1984 and there has been a world of change in how much planning is involved now versus then. At my age, it comes down to whether I want to be open to the changes and new technology and learn to deal with them or turn into someone complaining bitterly about how much better things "used to be."
When the current form of Fastpasses was introduced, I didn't like it because it forced me to decide months in advance what park I would visit on a particular day regardless of Florida's unpredictable weather. But it allows us to get Fastpasses for the most popular attractions without having to be in the park early before they are gone. We always visited Epcot in the evenings, and until Fastpass+, we never rode Soarin' or Test Track because all the passes had already been distributed by the time we got there. We are not rope drop people, we don't do the same ride multiple times and we absolutely hate lines. So the new system works well for us. Also, apart from the newest attractions, we have found it fairly easy to get the rides we want, even at the last minute.
We use mobile ordering to avoid standing in lines at quick service locations. Even when there are six of us, it's no problem to find a place to rest for a few minutes, figure out what everyone wants, and then just click the "prepare our order" button when we get there. Never waited more than five minutes for our order after clicking the button, although that may change as more people start using the service.
We loved the new Skyliner - I hope they can work out the bugs and expand the system if possible.
Are there things I don't like? Sure. I hate paying for parking at certain resorts where parking spaces are plentiful. I absolutely hate Disney's decision to sell the park "after hours" - both that and the parking fees seem like money grabs to me. We have been able to afford the price increases, but I worry about the impact on young families, who may never be able to visit. Our kids and their spouses go with us every second year in May, but that's because we bought into DVC early - there's no way we would pay the almost $10,000 cost of three studios at Saratoga Springs.
You can go to Disney without planning - I know people who have done so - and still have a good time. You won't get as much out of it as the people on these boards, but if you don't do the research, you probably won't know what you're missing. My brother-in-law called me three days before they went on an impromptu trip to Disney (my sister-in-law had some kind of work trip to Florida) and asked me how to get a Fastpass to "the tower of terrors." He didn't know what park it was in and had never heard of MDE. They got along just fine and enjoyed their two days in the parks.
