I can see why you and others have valid reason to have issues with FP+, and you make some good points. I'm not picking on you here either, but your comment above triggered a thought I've always had regarding people's dislike of FP+.
Putting the flexibility issue aside, which is a valid gripe, I think we can probably mostly agree, even without FP+ in the picture, between Extra Magic Hours, park opening and closing times, entertainment schedules, ADRs for meals (which many people make long before the FP+ 60 day mark), crowd calendars, recommended park days on the various blogs.......well, most people have a very firm idea of what park they are going to be in on what day, no? And they likely know this before the 60 day FP+ window opens.
Your analogy to meals is interesting, as there are a myriad of choices. But I'm not sure the analogy really applies to FP+.
So you know what park you are going to be in.....is it really that much of a mystery to figure out what FP+ to grab? Unlike dinner, there are not a myriad of choices. You grab something you know you are going to ride one way or another, and now you've got that guarantee in your back pocket. It doesn't mean you can't, and won't, ride other things. I thinks it's really as simple as that.
