No one is being forced to get any FP+, you can do what you like, do rope drop every day if you want, head straight for that ride you really need to do, try walk up to restaurants, do it all like the old days, there is nothing stopping you, I tried that with Beaches and Cream last trip, no spaces, not because of ADRs, but, because of walk ups, so I've done myself an ADR for this trip, I never do more than one ADR per trip, but, have done two for this one (breakfast at The Wave) if I change my mind I can cancel it 24 hours before as I did in May for a Star Wars Breakfast, dead simple using DME, much easier than calling up to cancel.
I first went in 1989 and have been a regular for the last 10 years, I like the changes, no more racing to Soarin' or Toy Story Mania at rope drop, but, I may give it a whirl on EMH mornings. And moaning about lack of choice for the fourth and after FP, why doesn't anyone ever seem to remember the old way of FP when you got your paper ticket for 4.30pm at 9.15am in the morning for the popular rides and being stuffed because you couldn't get another one anywhere until 4.30pm or whatever the time was. Get to the park at 10am and forget about a FP for Soarin' or TSM.
As for planning, several times last trip I decided to have a resort day, but, being me, at 10am I would decide to hit a park, perhaps because I'm not so entitled I would be happy to go to the park that had the most appealing FPs or get on the first bus and see what I could get, get nothing, no biggie, try another park and then park hop.
I agree though with the issue with tour groups and school parties, but, someone told me that you never see Brazillian tour groups from October to June as they tend to come when it is their winter (our summer) so if you don't like tour groups go then. I'd never do Spring Break after experiencing the first week of it last year.
You pays your money and you takes your choices, don't blame Disney, they are not forcing you to do anything beyond buy a park ticket.
