You'd be hard pressed to go on most of the rides and attractions as well as do sit down dining without any reservations/fastpass.
I do not see how World is any different despite the aforementioned notion of getting passes 2 months out and dining 6 months out. It is the exact same concept.
Regardless of the park, you become a slave to the schedule.
I feel like there are very few parks where you aren't a slave to the schedule in some way. If you want to see a show anywhere, then you're a slave to the schedule. If you want to get to the popular rides before they get crowded anywhere, same. While Disney is certainly more stressful than many places, I don't find Disneyland to be significantly more stressful than most other parks.
I can't speak as much in terms of restaurants, but in terms of attractions, I'd say that absolutely, FastPass/MaxPass is a big win if you use them. BUT even if you don't have/use them, the waits are usually about half what they are in Florida. It's also significantly easier to get FPs for everything you want than Florida. At WDW, it often feels like the park is working against you as you try to get things done. DLR doesn't feel like that, nor do the international parks.
If you simply don't like FPs at all and just wish they didn't exist, that's fine, but their existence and usefulness isn't going to change anytime soon.
At least at DLR if you don't want to worry about or can't get restaurant reservations you have solid counter service options and real world food options easily accessible on Harbor. DTD is also right there. Can't say that about WDW.
The parks are only as stressful as you make them. I'd say in general the international parks are less stressful and generally cheaper, although Shanghai and Tokyo can get super busy if you don't know which parts of the year to avoid (solvable with a simple google search) and Shanghai definitely does not have the ride capacity for the crowds it gets. Still easier, more pleasant experiences, even if they're packed to the gills. Maybe try those as an alternative?
