I don't care about Magic Bands...but as a local, I DO care about FP+.
I don't want to go to the parks and not be able to ride anything without a 2 hour wait because all the FP's are already taken...and I don't plan my day trips months in advance!
I'm not a local but I agree with you about FP+. With the exception of dining, I don't plan my trips months in advance. I like being able to be spontaneous!
